Hover hand has been well documented but isn't it time we had a thread dedicated to "hover arm"?
Shots where BBers in quite normal situations need to display a flexed bicep in a photograph.
I'll kick off with Soul Crusher - at a table of regularly dressed men, in a skin tight T-Shirt throwing a thumbs up because it gives him the opportunity to bring his bicep into the shot & flex it.
Note the way he brings the arm into the body to ensure it stays in shot.
