No homo is a phrase used as slang at the end of a sentence to assert the statement spoken by the speaker had no intentional homosexual implications. The phrase is also "added to a statement in order to rid oneself of a possible homosexual double-entendre". But sometimes, this just is not enough to be effective.
Dude, it's pretty hot in here. Do you mind if I take my pants off? No homo.
- Dude no way. No homo is not enough.
Dude, I got this weird spot on my penis. Do you think you could take a look. No homo.
- Bro, you're a fucking fag. No homo is not enough.
At the urinals - Sword fight anyone? No homo.
- What are you a fucking gay faggot!?? No homo is not enough.
