'T-Rex Arm' :
When laying in bed cuddling your partner, and one arm gets trapped under both bodies/pillow rendering it useless, it is 'T-Rex Arm', i.e completely void of movement and use.Thus, similar to a Tyrannosaurus rex's arm.

When a woman during sex puts a penny in the mans mouth and then pulls down on his erection.
If nothing happens, complain that he should have paid out

Such as that guy in the Twin Peaks movie. I don't think he was a bandit. He did have one arm though.

While recieving a blow job, during the first moments of ejaculation, the man slaps his penis in a side arm motion, spraying cum all over the woman's face.
Frank was on the recieving end of a nasty blow job, so he decided not to let it go any farther, and show his hooker who was boss by giving her a Cincinnati Side Arm.

A big arm test is a visual check of the diameter of a girls arms to determine if she will blow up in the future. If a girl has large arms but a small body while young, chances are she will become fat in the long haul.
person 1 - "damn, look at that girl on the beach, i'd marry her!"
person 2 -"nah dude, she fails the big arm test, shes gonna blow up like a blimp"
