Ultra is a state of mind. In many cases, it could imply a high level of faggotry, gay butt sex, homosexuality and sometimes even plain stupidity. Ultra men talk like women and in many cases hae a vagina. Presence of a penis is optional. Women can be ultra in many cases too. The only qualification is that they wear braces and glasses or just be downright fugly.
That kid is so ultra, he talks like he's taking it in the end pipe.
