Haha, that's funny 

Used in real life conversations or IM meaning, "I'm pretending that's funny, but it's really not" or, "I have not idea/I don't care what you just said, so I'm gonna say this." Also sometimes used with lack of enthusiasm in real life to show sarcasm.

Similar to lol, lolocaust, and haha.

Frank: I just threw an apple at my sister! LOL!
Donnie: Haha, that's funny.

Meaning: What the fuck, you suck at humour.

Joe: So, I said, "No, that's my seat, yours is over there."
Jake: Haha, that's funny.

Meaning: I'm bored, I'm gonna go get high.

dude, that's not funny, my mom's dead 

The ultimate response to the ever classic insult 'Your mom.'

Person A: Hey dude, sup?

Person B: YOUR MOM IS UP!

Person A: Dude, that's not funny, my mom's dead.

Person B now either believes you, is confused/apologetic, or smart enough to prove the ultimate response to this; Yeah? I really like that.

Cult of Funny 

Abbreviations: CoF

The Cult of Funny is a cult with its roots in the 'exurb1a' discord server based around a popular YouTuber who covers topics such as Philosophy and Science. The CoF was founded by Boomerstein, with the initial purpose being surveillance and memes. It quickly grew in numbers until many high-profile members of the server were indoctrinated.

'Oh no, the Cult of Funny is getting stronger. Soon they will consume the server.'
