Red Lipped Ninja

"Jane forced him to munch the rug last night and he ended up looking like a red lipped ninja."

"Bobby was going down on Sarah when she totally red lip ninja'd him. What a bitch."

Ninja Movie 

Ninja Movie n. Arguably the only kind of movie that matters. Particular high points include the films produced by Joseph Lai's IFD Film Arts in the mid-1980s.

"Yo dawg, grab that bag o' chips and a couple Colt 45s. We gonna watch a NINJA MOVIE."

Ninja Butler 

The Ninja Butler is a great and mysterious being... always using his power for good. He moves undetected in your home doing good deeds and bringing joy to all. His most common good deeds are bringing cups of tea, flipping the mattress and putting clean sheets on, and cleaning the kitchen sink.

His kindness knows no boundaries... his expertise knows no equal.

He's currently thought to live in northern England.

She looked down and saw a hot cup of tea that seemed to have appeared out of nowhere... the Ninja Butler strikes again.

a woman who swiftly and silently cleans one's living quarters, often without being seen or even noticed, so much so that said living quarters seem to have cleaned themselves. payment is left in the open, and missing payment is a definite indicator that the ninja maid was there and the job is done.

Stacey is a ninja maid!
