Whenever you eat a large amount of food at once.
1st person- "Dang, you should have seen Derek this morning at breakfast"
2nd person- "Yeah I know he really Jethro'd It!"

Get the Jethro'd It mug.
A piss poor attempt at a pick up line that actually insults the target well beyond any woman's ability to not kick you square in the balls.

A 'back-handed' compliment.
'Man what happened to him.?'
'Dude, he went to talk to that girl and seriously jethro'd on her!'
'So, why's he on the floor?'
'She punted....'

well, like you, you're a big girl...
WHAT!?!?!
No, like you know, a large body structure...
ARE YOU KIDDING ME???
No, like, your really there up top...
