What I think of when I hear the "gets on my t!ts" phrase;

"No wonder you're always gettin' slapped in the t!ts!"- is an improv. line by a friend in my younger brother's movie. His character said it to a guy who regularly tried to hold-up his disposals store with a butter knife. He was then told by my brother's character, also being held-up, "I'll give you the money, so long as you use it to buy yourself a decent knife from our quality selction". So, the guy went into the changing room to 'try them on', mimicking stabs in the mirror. He eventually said "No, they're just not me" to the hunting knives, and "I've got a routine going with this", about his butter knife. So, he gave the money back and was told not to come back unless he has "a decent knife next time".
