T-Rex 

Just like a T-Rex, you eat/devour your girl without using your hands. Bonus points for growling and screaming

Her - I want you to go down on me tonight
Me - Oh I’ll T-Rex you baby

t-rex 

When you are fucking a girl from behind and feel a sudden urge to eat. You bring your elbows to your abdomen and swing your arms like a t-rex. At the same time you lean over and bite your bitch on the neck. Since your arms are essentially useless, you now must keep her down by clamping harder and pushing with your neck. This sex position is similar to a T-rex when feeding.

I don't know what happened the PCP hit me, and I just t-rexed the bitch.
Damn bro, what happened last night, I walked in on you t-rexing some bitch and growling.
