G.I. joe or G.I.jane
a person who talks so much behind your back it’s like they're trying to get you fired just for fun.
My teacher is a G. I. Joe. She told my principal I was a troublemaker just because I got a B.
My friend is a G. I. Jane. She told my crush I was a joke just to make him sad.
My mom is a G. I. Joe. She told my dad I was a disaster just because I spilled juice.
