noun, na-adjective
Strongly derogatory slang for a person who is extremely lecherous or obsessed with sex. Often used as an insult or in a joking, exaggerated way among friends.

すけべ is a milder, more common slang term for a lecher or pervert. どすけべ adds the intensifying prefix ど-, making it stronger and more vulgar.
Formed by adding the intensifying prefix ど- to すけべ (助平), a slang term for a lecherous person. The exact origin of すけべ is uncertain, but it may be related to the word 好き (suki, 'liking') or a contraction of すけべい心 (sukebei-gokoro, 'lecherous heart').
