Ninja Chuck

To throw up so violently that it causes one to strike a ninja pose.

Bill drank too much last night. He ended up ninja chucking his beer all over the bathroom.

I just ninja chucked so hard I punched the wall.

Rusty Ninja

After a sporting event; when your teammate is washing his hair and his eyes are closed, someone sneaks up behind him and checks his oil with their thumb (quickly slips a thumb in his ass), then runs off before he is able to rinse the soap away and identify the clandestine violator

After the game someone gave John a rusty ninja. John was attacked by a rusty ninja after the game. Be careful, there's a rusty ninja in there.

ninja toes

the art of sporting socks with thong flip flops, which in fact look like the traditional footwear worn by Ninjas

Ninja Boner

A ninja boner is an erect penis that you must stealthily conceal whilst moving, which involves disguises and clever use of shadow and vegetation.

Often required when the words "Give it a minute" will not save you.

Last night Jen gave me such a ninja boner at the party, I had to creep around the outside of the garden in the dark to get a drink.
