lip locked 

This happens when a dude that has braces on his teeth is going down on a girl that is quite hairy in the nether lips and his braces get ensnared in her pubes, thus locking his face lips onto her downstairs lips.

-Hey, did you hear about Timmy?

-Yeah, I heard he went down on that random girl at the party, and they got lip locked.

-I guess that's why you need to check before you munch.

-True.

lip-locked 

(v.) When someone does something so unattractive that your vagina (labia majora) literally sews itself up

I was lip-locked after his hot, stinky breath made its way into my nostrils.

Liplocked Gridlock 

When traffic is stalled at a signal because people in the first car are too busy kissing to notice that the light ahs changed.

The people in the car in front of us was kissing at a stoplight and didn't notice that the light was green which caused a Liplocked Gridlock.
