a short sex act (performed when eating out a guy's ass from behind) whereby the ass-eater momentarily services his cock and balls fruitbowl style before going right back to eating his ass.
important note: by dwelling any longer on the junk, it is no longer a licketysplit but rather an entirely different sex act: sucking cock from behind. the licketysplit is a quick acknowledgment of the dick and balls but is still really all about the ass, a side dish to the main course.
while hungrily eating out jeff's ass, martha quickly ran her tongue down to his balls and cock giving him a licketysplit before resuming tossing his salad.

FRIEND A: "Did you just take a stealthie of me?"
FRIEND B (turning phone around): "no I was just using snapchat's new filter, see?"
