"When an individual decides not to attend an event and/or social gathering because they have to sleep, call their girlfriend, masturbate, study, go to another friend's house (i.e. they are a biatch)."
Alternate meaning: "To mess up." or "To perform badly on some operation."
(Created by Nate Dogg of Escondido, CA. You cannot step biatch. Recognize.)
Nate: Dan, don't dildo out on us again!

Nate: He dildoed out on us.
Daniel Bro: Well, that is his job as our friend.
I totally dildoed that wave.
