Trying to sum up a bit and add my 2 cents:

The "standard fling" or the "momentum fling".
Easy enough; this is when you place portal A high on a wall and then step out of it. By then placing portal B where you would land, you fly out Portal A with great speed.
The normal fling taught in Portal single-player yes. Can probably be described shorter:
Normal fling
Jumping straight down a horizontal portal and exiting a vertical or slanted portal converting your vertical momentum to lateral momentum.

The "freefall" fling.
Just a twist on the momentum fling; portal on ceiling and floor; you build up momentum and eventually place the ceiling portal somewhere else and fling with all that built-up momentum.
I like the name "terminal velocity fling" better, as suggested by someone else in this thread as well.
Terminal velocity fling
Setting up an infinite loop of portals to gain terminal velocity and then replacing the top portal to exit at a new point at maximum speed.

The "trajectory" fling.
Starts as a momentum fling, but you place a new portal when you land and go through portal A yet another time (or more). Since your entering trajectory is different each time, your angle leaving portal A changes each time, giving you more height/distance, perhaps.
Trajectory fling doesn't have to be that complicated. It doesn't have to be "looped". (Case in point: the original trajectory fling in shmitzchamber01 is most easily done by doing the loop, but can be done in a single pass as well if you get the velocity from the initial entry right. Example: http://www.youtube.com/watch?v=P983h0kevFk.)
In my opinion trajectory in it's basic form should be described as:
Trajectory fling
Purposefully falling through a portal at an angle in order to exit the other portal at an angle.

The "step" fling.
Done to gain momentum, or height. You are on top of a wall. Place portal A on floor at top of wall near edge; place portal B below on floor at bottom edge of wall. Jump through portal B, come out portal A, and in mid-air maneuver to fall to portal B again. Every time you do this, you leave portal A faster/higher.
Trying to simplify the description:
Step fling
Two portals are placed closed to each other but at different heights. Repeatedly exiting from the upper to fall in to the lower increases momentum.

Portal A on floor under whatever you want to get over, portal B on a ceiling somewhere. Step into portal A, and while dropping out of Portal B place portal B under you. Result; you fly vertically out of portal A and land on or over your target.
Jump fling
Jumping through a floor portal on your level to come out of a ceiling portal and then quickly replacing the ceiling portal to the floor to come jumping high out of the original floor portal.
(Meh maybe not much simpler description after all.)

When you fall into one floor portal in order to fly straight up out of another floor portal elsewhere, I call that "bouncing." The name is especially apropos if you do it multiple times using the same momentum.
I think that actually covers two different, thought related, flings:
Bounce jump fling
Putting two floor portals on a level below you to fall through one and come jumping out of the other.
Bouncing flings
Repeatedly moving portal sets using the same original momentum.

Don't forget the always useful "crouch fling".
It's basically a regular fling (or double-fling) but instead of just
shooting for the center, you utilize the "Portal Tunneling" feature
and jump-then-crouch into the EDGE of the portal. The Portal Tunneling
sucks you into the portal faster than you would go through with the normal
jump giving you some extra momentum for a fling with more distance.
I think the term "funnel fling" is more appropriate then to be honest, since it (ab)uses portal funnel to gain momentum. I don't think you need to croush as well, though you get more extra momentum if you do crouch. It's a tricky technique for sure since it requires fairly accurate aim and timing to pull of right in my experience.
