A point where a man has masturbated so many times at once that the skin on his penis becomes sore and red. (three times a day is the recommended max.)
Tony: Dude, after my girlfriend dumped me I began to masturbate alot. So often that I began to chafe-off.

Chris: lotion usually helps that. Try is next time you do it.
