Tree Trunk 

The material of a man's penis. Usually a rough and rigid type feeling like the bark of a tree. Common with old men. When one man is turned on, instead of cum; the penis will let out sap- but the sap will have a difficult time coming out.

My husband and i had sex for the first time, and he had a Tree Trunk.

1) A warning that a man might not be adequately equipped for the task at hand.
2) An attempt to convey a sense of pride in one’s inability to put down a Twinkie.
3) An extremely lame attempt to separate buttocks by ethnicity, and avoid the obvious connotation of a complete lack of self-control.

Do not approach Gloria from behind without a helmet on as she has too much junk in the trunk.

it means take a shit. you pop trunk when you have to imminently poop. so when these gangstas are threatening to "pop trunk on yo azz" or whatever, just laugh, because they think it's something hard-ass
