Joe and Bob are watching porn.
Bob: Wow, I'd totally do that chick. And those red heels of hers, wow, she just looks...
Joe:...so last season.
Therefor, Joe is NOT thinking straight.
Used on someone who analyses everything in a homosexual way. Can be used on straight and gay, male and female.
John: Yo pete, come in the back!
Pete: Fuck no you fucking homo!
John: What's got HIS dick in a twist?
Bob: Don't you know? He can't think straight...he heard "cum in the back"
John: Damn...thats a serious case!
