When an arrogant diva type athlete (usually a wide receiver who thinks he is better than he really is)runs an outside route gets cracked back and his chinstrap, ear pads, or in a severe and delightful Billowing helmet flys off.
Edge rusher: Hey that 88 has been talking head to you all night. What are you gonna do about it?

Safety: Next time he runs a bush league hitch, I’m gonna knock his head off.

Next play
Edge Rusher: Wooooo! You knocked that baby’s bonnet off!

Safety: Chup! I told you he runs that weak route again, he was going to Get Billowed !

Get the Billowed mug.
Someone who feels it necessary to create large clouds when they vape.
Joe is a billower, that should tell you enough!
