The action of a guy or girl squeezing a girl's tits from behind or (if you have the guts) from the front. When this action is done, you must scream, "Orange Juicer!" which is a person who has done the action of "Orange Juicing" before.
Dude, I just finished Orange Juicing the new girl! Im an Orange Juicer now man!
to irrationally associate something with a past memory
No. You're just orange juicing again...
