When an arsehole is not correctly wiped and after a few hours the left over excrement goes dry and crusty, thus leavin crusties attached to bum hair.(note after exercise sweat may cause these to dissolve and let off an unpleasant smell)
He was in a rush and did not wipe his ass properly, after his nightly training he realised a real bad smell was comin from his rear end. and thn said to his friends "oh shit i hav crusties"
