G1O
G1O is when a guy says he's going to ‘grind one out’ to his friends to hide the fact he needs to take a leak somewhere embarrassing. It’s a lie, and it’s usually a bad one.
'I’m going to G1O!' he yelled as he ran out of the mall.
'He said G1O and ran into the gas station like a scared rabbit.'
'G1O? That’s what he said before he vanished into the airport bathroom.'
