"Shit dogg I heard you banged Lil' Kim last weekend. She's a nasty slut and all, but she's pretty hot and has a nice rack. What you gotta say for yo' self playa?"
"It itches."
another term for scabies. usually given before actual diagnosis (scabies is often misdiagnosed as dermititis). the bitchy itchies really suck and causes constant horrid itching which leads to becoming incredibly bitchy all the time.
this term could be used to describe any horribly itchy rash that seems to not go away easily, but the nature of scabies suits it well.
