D-Rex 

When a man alerts his counterpart(s) about an impending sexual act by dropping his penis on a surface hard enough to alert them through ripples in the drink in front of them (often accompanied with the phrase "Hold on to your butts!")

John totally D-Rex'd me last night before ravaging me more furiously than a frenzied ape. I got him back the next day with the ol Raptor Vag.
