The oh-so-lovely process that sometimes occurs in females about 2 weeks after their periods, in which left overs from the previous period leak out. A sludgy, dark-brown discharge leaks from the vagina and frequently stains underwear; making them look suspiciously shit-stained. Though the flow is not as heavy as a regular period, it is still damn annoying.

A low-life toxic personality who spreads their poison and contaminates the innocent. Sludge is human primordial ooze. Teenage girls often gravitate towards sludge. The sludge soon slimes all over them and the next thing they know the girl's hooked on crack. The trick out stage is next, where Mr. Sludge puts her on the street. She becomes a crack ho and he profits from the dual trade. Advice for dealing with sludge: run in the opposite direction or shoot on sight.
