F.N.B.O
When you take off all your clothes and give a full-on cumshot right in front of someone who’s too stunned to react
My cousin walked in on my F. N. B. O and just stood there like a deer in headlights.
I did my F. N. B. O in the middle of the school hallway and got suspended.
My girlfriend’s brother caught me doing my F. N. B. O and now he sends me memes every day.
