hottzy is a versatile word. Always used in sarcastic ways, it usually refers to something that is dumb, ugly, stupid, really lame or gay. Pretty much can be used to describe anything in a bad way. Something that isn't cool.
"My hair is so hottzy today."
"Ew, wtf is her face? She is so hottzy looking."
"Stop acting hottzy."
"She was acting reetzy and being real hottzy. Her hair looked reall cutezy too. I'm like, 'yeah your reall good'."
