2D & 1/2

When 3 dimensional graphics are created in 2D graphic programs. Usually, CGI and 3D graphics for film, television, and video games are created in programs like Lightwave and Maya, but 2D & 1/2 utilizes computer programs like Adobe Illustrator, Photoshop, or Corel Draw to mimic them. Though graphics created in these programs can only be applied to two dimensional applications like magazines, photographs, or any other item with a flat, static surface because they not to truly contain any virtual depth.

Many of those trendy glass/gloss logos are 2D & 1/2 because they weren't created in 3D graphic programs.

2 1/2

2 1/2 was created by a kid in 2005 at Creekwood Middle School. Many have asked what 2 1/2 is, but the true responce is "Only the special may comprehend the power of
2 1/2." Only the creator can choose who the special is, and the "power of 2 1/2" means 2 1/2 is very powerful.

2 1/2 is the most powerful number, so only a few can even comprehend it.

1 2 Punch

The act of two people doing sexual things with a girl simuntaneously. Sort of like a gangbag or doubleteam. Other definition would be 1 guy starting to have sex with a girl, then pulls out and has the other guy finish her off.
