pronounced Ba-see-li-ing. The act of laying in bednaked, and masturbating until you climax. However the object is to cum high into the air (aim for the ceiling) and flip around so the cum lands on your own back.
Guy...i was so horny last night that I was basiliing. After I came, my back looked like a cum-bath!
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.
