Rule 97 

Rule 97 of the internet, the combination of the two rules 34 and 63

Rule 34 : If it exists, there is porn of it.
Rule 63 : If it exists, there is a genderswapped version of it.

Rule 97 (34 + 63) : If it exists there is a genderswapped porn of it, if not it is in the making.

Bro1 : Bro, I just found a genderswapped photo of Peach squishing Marios titties
Bro2 : Shit bro, rule 97 strikes again

Never, under any circumstances, make a dragon cry.

Recently a neighbor broke rule 97, we haven’t heard from him since.

976 rule 

the physical attractiveness of a person one's never seen before is significantly lower than the appeal of their phone voice. (the rule is based on the principle that "976" phone sex operators are generally unattractive women in trailer parks.)

"I'm not going out with your sister unless I see a photo first: I've been burned by the 976 rule too many times, and ended up on dates with monsters."

Cheeks 

An Irish phrase meaning shit, derived from ass
(Not to be confused with the literal description of one's buttocks)

"Did you hear the song Aylek$ dropped?"
"Hardly. Her music is absolute cheeks."

"My boyfriend say LaFlame is cheeks."
"Tell your boyfriend I said it's his mixtape that's cheeks."
