look up any word, like fleek:
 
1.
to get sucked off by a woman and just as you reach the point of no return, pull out and make her smile broadly before chucking your baby batter all over her enamel.
John: I was getting sucked off by Stacey last night and finished off by giving her a bit of teeth whitening. Bitch looked like an Arm and Hammer model afterwards.

Adrian: Dude, that is sweet!

2.
the act of swallowing after fellatio.

it is said that semen is a natural way of teeth whitening, so swallowing after performing the act of oral sex will only allow for the color of your teeth to improve.
