Bradford went to shake it like a polaroid in the bathroom, but found his brother already developing his own polaroids.

shake it off

After a male urinates, he doesn't wipe like a female would. Instead he holds onto his genitalia and "shakes" it, so as to dry off.

He had to (shake it off) so he could put it in his pants.

*glancing around stupidly at your friends, miming the shaking off* "(SHAKE IT OFF)".

~(shake it off) can also be used as a dumb immature joke, as seen in example number 2~
