The absolute BEST fucking comeback to the any insult in the world, including "ur mom gay". The possible end to ANY conversation in the world, even if it's NOT something you can say it to. Currently, the only possible way to defeat "no u" is YFM's "UNO Reverse" song, which doesn't work if the opponent doesn't know the song; so don't take it as a complete win. Here are some possible examples:
Example 1

Bob: Hey wanna watch gay porn?
John: Bruh what? I'm not gay!
Bob: Oh sorry, forgot that ur mom's the gay one.
John: What's that even mean?
Bob: So ur mom gay.
John: no u
Bob: *fucking dies*

Example 2

Phred: Hey Phil?
Phil: Yes?
Phred: ur mom gay
Phil: no u
Phred: BAM! UNO REVERSE CARD!
Phil: Dude, I already said "no u"
Phred: Wait, you don't know the "UNO Reverse" song?
Phil: Uhh... No?
Phred: Fuck. *dies*
Phil: wtf just hap-

Example 3

Bill: Hey pal what's u-
name: lets just get it over with
Bill: Wha-

Bill: Dude... What are you talking ab-
name: JUST SAY "NO U" YOU IDIOT
Bill: WHAT'S WRONG WITH YOU BRO?
Jack: Hey guys, ur mom gay!
name: oh i think i read the script wrong
Bill: What?
name: no u
Jack: BAM! UNO REVERSE CARD!
name: FINALLY *fucking dies*
*silence*
Bill: WHAT THE FUCK JUST HAP-
