A karate-chop hand motion delivered to a guy's crotch. Was originally invented to be done with an actual tomahawk, but it was then decided that the receiver might not want to be sterile for the rest of his life. If you try it, ladies, just make sure the guy is into being dominated...
When someone gives you a random link and it is a YouTube video of someone getting a Tomahawk kill from across a map in the highly acclaimed FPS, Call of Duty: Black Ops.
Person 1: Anyone know how to fix a toilet u-bend?
Person 2: Here -shows Tomahawk Rick Roll clip-
Person 1: I believe I just got Tomahawk Rick Roll'd.
A sexual position involving newspaper, a diaphragm, and a large penis. First you get the women to wear a diaphragm to avoid pregnancy. Then you lay newspaper all over her vaginal area. Then the male starts masturbating rapidly, and ejaculates all over the newspaper covered area. Right when the man ejaculates, he should shove his erected penis through the newspaper, and into the women's vagina. Afterwards, you clean up, and can now remove the diaphragm.
When a well endowed man drops his hard erect penis on the face or forehead of one of his buddies while several people are present to laugh at the act. The ultimate Tomahawk Kawk Drop is performed when the penis is rather dirty and seemingly has the smell of salt and vinegar.
Boomer: Dude you were so wasted at that party last night!!! Do you remember doing a TOMAHAWK KAWK DROP on Zach's forehead?!?!?! That shit was so funny!!!
Tom: Yeah...I was drinking non-alcoholic beer. I was aware of exactly what I was doing!
