1. train a boyfriend to live (cleanly) in a house.
2. to subdue, tame a boyfriend.
Works particularly well when training a boyfriend to put the toilet seat down (since in regular useage housbreak is to train pets to excrete outdoors). Also useful when keeping a boyfriend on a tight leash (see friend ditcher) or when teaching other domestic responsibilities, like making the bed or washing dishes.
3. (adj.) "housebroken" Not nearly as derisive as "whipped" therefore mostly used by women of their significant other.
Your boyfriend really comes straight home after work? How long did it take to housebreak him?
