Fap dialing is the act of accidentally calling someone while masturbating or engaging in a sexual activity. This commonly happens when one has his/her phone in their pocket while masturbating and their body accidentally dials a number and calls it.
"Dude, I'm in huge trouble, I accidentally fab dialed my mom last night and it left a voice mail! She heard everything! Dang, I hope I never fap dial anyone again."
