K-O-Y rule 

k-o-y rule is a simple and effective method on popular applications such as Facebook chat or AIM to get annoying people to fuck off. Basically, all you do is respond "k", "o", and "y" after everything the annoying person says. They will realize that your one letter responses seem to show lack of interest in the subject at hand. Repeat if intended subject isn't fucking off

K-O-Y rule in action:
Example 1:
Jack: Hey Phillip!
Phillip: k
Jack: Wanna hang out?
Phillip: o
Jack: Well I didn't mean to be a bother...
Phillip: y
Jack: I'M LONELY OKAY?
Phillip: k

Example 2:
David: ...and then Julie started acting strange
Phillip: k
David: But I didn't finish.
Phillip: o
David: Will you stop with that??
Phillip: y

11 O'Clock Rule 

The time that a party really "begins", no matter what scheduled time the party was actually supposed to start previous. This is the time that, without fail, droves of people show up all at once and a party can go from almost non-existent to full-fledged rager.

"Man, this party was so lame for like the past 3 hours, now it's insane! (Looking down at watch, seeing it's around 11 PM) 11 O'Clock Rule, happens every time!"

New Rule of Thumb 

The new rule of thumb is the publicly sanctioned male violence against women that do not comply with the current ideology. The Biden administration has exacerbated this by claiming attacks on certain groups.

Swimmer Riley Gaines just got assaulted by a male for speaking up about women’s rights. This day and age, the new rule of thumb allows males to beat women for speaking.
