The process of sticking your dick in a women's vagina briefly for a few seconds to make your tip moist.
Done usually if the woman suddenly needs to go and you only have sex for a few seconds.
"Dude, me and Sydney were going to have sex, and I started to fuck her, but then her mom called her home cause her Grandma had a seizure. It was basically a wet tipping sort of sex only deal"
to have sex, when you get your tips wet, that means you dipped your penis in a (wet) vagina. OR you could have fingered someone and got your tips (finger) wet.
when you're holding up your phone and making faces at it, as though you are taking a selfie, but you're really taking a picture of the person across from you or the wall or anything else that seems interesting but you don't want to be caught dead taking a picture of.
This action is often made more convincing by wiggling the eyebrows or opening the mouth, to pretend you're trying to get a Snapchat filter to work.
FRIEND A: "Did you just take a stealthie of me?"
FRIEND B (turning phone around): "no I was just using snapchat's new filter, see?"
