lip lap

A rare way of kissing/snogging. Not many people use this way. They prefer sticking their tongues down the other person's throat.

I thought that she was going to do lip lap but she wanted to do tongues.

1st person: How did the kiss go?
2nd person: Terrible. I ended biting her tongue and she dumped right there on the spot.
Kissing veteran: Lip lap is harder than you think. You've got to time it just right!
