Haachi
A Haachi is a guy who thinks he's hot, but he's just a sweaty, vaping, cheating mess who makes everyone around him look good.
My friend got called a Haachi because he cheated on his girlfriend and then copied my essay.
That guy at the gym is a Haachi, he vapes, flirts with everyone, and still can't do a sit-up.
My math teacher said I was a Haachi for cheating on the test and then flirting with the teacher.
