Bleach-blond frosted tips, maintained for one to six months depending on the league's mercy, occasionally timed to coincide with a wedding or bachelor party for maximum photographic permanence. The goatee-frosting variant exists and is worse. A time machine to 1999 that only the loser has to ride.
The long haul: this is not a one-afternoon sentence. With a time commitment of one to six months, the punishment keeps paying out (for everyone else) long after the season ends. Long sentences need a written end date and a league-appointed enforcer who checks compliance.
