"Leccaculo" is an Italian derogatory term for a lackey, a servile adulator. It is a compound word that literally means "ass licker", because Italians imagine lackeys so prone to satisfy the object of their adulation (a boss, a professor, etc.), that they could lick even the dirtiest part of his body.
