When someone's foot/leg photobombs a picture, but not the rest of their body or face.
Basically photobombing but specifically with feet.
A portmanteau of the words "foot" and "photobomb".
Jack (to gf Jill): Jill, you're in yearbook....snap a few shots of me? :)
Jill: kk. (takes out camera, starts taking photos)
Jim: (sticks foot in front of camera lens)
Jill: Jim, you totally footobombed our picture
Jim (with trollface on): Yeah I know... LOL
