Theo 

A person who everyone should be very cautious of. He is an entitled, really manipulative and coersive person, who seems like a nice guy at first but this is only a tactic to get close to you. He pretends to be a feminist but is super sexist and mysogynistic. He is the epitome of small dick energy.

I thought that he was nice but I guess he's just another theo.
You're so sexist that you sound like a theo
