Degasmic is an adjective that describes something that can and/or will stop an orgasm. It may also be used to describe something that can be the opposite of an orgasm or may prevent one from happening.
"Dude, your mother is so degasmic."
"Girl, I want you so bad, you are definitely not someone who is degasmic."
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.
