Bragging to
your friends about the skank you banged, then crying alone because she broke
your heart.
It is guimo when someone you try to
intimidate stands up for themselves and you then cry because they don't respect you.
Person 1: "I spend all my time at the gym so I'll look good and people still don't respect me or acknowledge how tough I am :*( "
Person 2: "Wow. You are a guimo."
