splitscreen 

A splitscreen is a phenomenon caused by being confused by two members of the opposite (or same) sex.

For example, liking two girls and being confused as to which one to pursue.

"Shit man, I'm lying here in bed, and I got a splitscreen."
"I keep thinking about this splitscreen."
"Chloe and Katy have given me a splitscreen."

Split Screen Mind 

When people don't apply to themselves, the same standards that they judge others by. People with this affliction repeatedly fail to live up to their own publicly proclaimed standards.

Richard:

"How bout' that... there she goes again, condemning the barbarous laws of that developing nation while supporting capital punishment in her own".

Joyce:

"Looks like she's suffering from a split screen mind".

Split Screen 

A sex move that is taking campuses across North America by storm. It is the act of playing a multi-player video game with a girlfriend/acquaintance/random girl while doing her from behind. Doggie style is a must as the TV must be visible for both patrons involved.

Did you bang her?

Fuck yeah. We did the split screen for like six fucking hours. First to Mario Party 3 and then Goldeneye. She was Oddjob and I was Baron Samedi.

Split Screen Reality Wank

When you have a wank over someone you know who looks like an actress in a porn film. You split your screen to show the woman you know on one side of the screen (perhaps a Facebook photo) and the porn video with actress who looks like her on the opposite side.

Brian: "You coming down the pub mate?"
