1.) To slide a layer of yucky saliva on something. To taste something. 2.) A trace of something. 3.) A treasure, prize or money of some sort, as in, you caught a lick. In the world of pirates, it's a booty. When you come up on unexpected money. 4.) A lick is musical idea, but often it's incomplete. It might be a fragment of a solo or a portion of a riff. By itself, it doesn't usually become thematic---in fact, a lick that forms a theme essentially becomes a riff. A lick combines with other licks to form a complete musical idea. Because a lick isn't the main theme, it doesn't have that same association with the song, and so it's transferable: it can be used in other songs without necessarily having to allude to the original.
"Black Dog" by Led Zeppelin also uses a great lick as its main riff. They play it in different keys, but it's still recognizably the same idea. You could imagine that melodic fragment as part of a solo, but by using it as the foundation of the song, Led Zeppelin makes it a riff. I could see someone playing this at the end of their solo, and I'd think it was both clever and funny.

When you have eaten a big dip of extra spicy habanero mixed with sriracha sauce mixed with ghost pepper flakes and your ass is boiling to a loud howling whistle, it's time to call on the porcelain gods and let that ass simmer down now.
A brothel keeper in charge of the nookie. She makes the deals. She keeps the books. She pockets the money and THOT spreads'em. Mary Ann Conklin (1821-1873) was a shrewish madam who cursed like an Irish sailor in several languages. She ran the Felker house in Seattle, a brothel that serviced sailors and lumberjacks. She built a strong no-nonsense reputation. Once one of her customers asked for a receipt and she answered by flinging hot firewood his way.
