Old cool Tony said "Seeja, don't wanna be ja", as he drove off with his ladies in his low rider LD pimp mobile.
Slang for oral sex on a woman's vulva. Code for cunninlingus, cunny liptus, shortened to liptus. Many times used in place of calling someone a cunt especially when in public where cussing would be frowned upon.
