'In The House' Star Maia Campbell -- Arrested At Waffle House & Burger King ... Calls Cop a Fa**ot!

LL Cool J's ex co-star Maia Campbell should really try ordering in -- she just got busted at a restaurant for the 2nd time this year ... most recently for causing a drunken scene at a Waffle House.

Cops in Riverdale, GA tell us they got called to the restaurant last weekend when the former "In the House" star was allegedly wasted and causing a scene. Officers gave her a chance to leave on her own, but she refused -- and then left in handcuffs ... and got booked for disorderly conduct.

The 38-year-old also ended up in an Atlanta cop car last month -- when she went off in a Burger King. According to the police report obtained by TMZ ... she cussed out a family, accused their child of stealing her wallet, and called the arresting officer a "fu**ing fa**ot!"

Cops say she denied using foul words, and claimed to only speak the "King's language" -- which is either some strange BK dialect or maybe she meant the Queen's English.

Hard to tell.
