Just when you figured out how to accurately drop ''fo' shizzle,'' ''crunk,'' and ''chickenhead'' into casual conversation, here comes Dizzee with a boatload of confounding British hip-hop slang. To assist your decoding of his debut, Boy in da Corner, Dizzee has assembled a mini-dictionary. SCREW FACE (heard on ''Stop Dat''): ''A mean mug or a mean face.''
CHOPPAH (heard on ''Fix Up, Look Sharp''): ''That's a knife.''
CHAPS (heard on ''I Luv U''): ''You know how a lot of rappers have chains? Chaps are the big fat chain links. Like a big gold bracelet.''
FITNESS INSTRUCTOR (heard on ''2 Far''): ''On the mike I keep it interesting, keep it exciting, keep it moving. Master of ceremonies.''
SKET (heard on ''Jezebel''): ''That's a jezebel. Like a slut or a ho.''
BATTI (heard on ''Stop Dat''): ''Your bum. Mainly referring to girls, just in case you were wondering.''
BATTERY* (heard on ''Jezebel''): ''To get batteried. You chose a messed-up word. That's like lineups. Group sex, one girl and a bunch of guys. A gang bang.''
