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.
