A mobile phone call placed accidentally and unintentionally, usually from the Send button getting pushed during normal movement while the phone is in your back pocket (next to your butt).
"My phone rang about five times in a row and there was nobody there. Each one was a buttcall from Tricia!"
A condition of tightness or numbness in the testicles that is felt after fully inserting them inside another person's anus for a prolonged period of time. The intensity and duration of buttballs is dependent on several factors, including but not limited to the size of one's testicles, blood pressure, tightness and dilation of the host's anus, and duration of insertion.
"Damn Tone, you dunked yo nuts in that bitch's ass for over 20 minutes! You must have a seriouscase of buttballs."
This is when some dick has his cell phone in his back pocket or just placed on the sofa and either they sat on it or someone else sat on it hitting the speed dialer to your cell phone. Of course they have no idea they called your number but you get to listen to all their BS.
Ever have your cell phone ring around 2:00a.m. you pick it up then answer, hello, hello, hello...all you hear is a bunch of people talking and perhaps loud music in the background. You think you recognize one or two of the voices but then you hear your name and they are saying some pretty rude things about you. Well then you've been "butt called".
A butt call is when some clueless moron keeps their cell phone in their back pocket without locking the key pad. They sit on the phone, thereby using their buttocks to dial YOUR cell number.
Ever have your phonering at 12:30 am and all you hear is loud music and unintelligible voices - some of which may or may not be those of someone you know? Then you have been butt called.
