A Crusty Harold is a sexual act where a male fornicates with another male or females anus until ejaculation occurs and the semen is left to dry or "crust" on the anus over night. It is then licked until clean the next morning.
Koza totally gave that girl a Crusty Harold and the crust that accumulated over night was so prominent that it took more licks to get to the center of the tootsie pop than he thought.
