Greiging 

Getting utterly shitfaced, generally way too early in the night, so much so that you break into impromptu acapella show tunes, loudly, with a likely outcome of very limited recollection the next day.

Omg I was Greiging last night - and soo out of tune - but it was worth it. I’ll be Greiging again tonight!

Gregging 

'Gregging' is the process by which an individual masturbates into a hat. Though this is its definition, it can also be used to describe an individual resting his penis in a hat, and/ or using the hat to masturbate. To 'Greg' someone is to steal their headwear, and perform one of these heinous acts using it.

Example 1)
It has commonly been used to make amusing adjustments to songs:
"Gregging,Gregging you... filling up your beret with my penis"

Example 2)
Ray: "Man, what the fuck is up with your hat?"
James: "you wont believe it, Some punk gregged it last night at the party!"
Ray: "Ouch, dont worry about it, weve all been there before"

Example 3)
Mark: "Hey, look at that blokes hat, you want to greg it?"
Bryn: "Hell yeah!, ill go first"
30 minutes later
Man with Hat: "Bollocks"

Greging it

Masturbating all day non stop for the sheer purpose of getting rid of boredom, or in some cases expressing your hatred of Sara Palin through sexual pleasure.

Not to be confused with the phrase "gregging it" which is masterbation into a hat.

Examples: 1)"I was so mad when Sara Palin but out going rouge that I just had to start greging it."

"Today I looked up pornography on the internet and started greging it because I was bored"

2)"Hey did you here what Sara Palin did the other day?"

"Yeah, i'm going to protest by greging it."

A person who would start gregging it would be someone who goes out on weekends and attempts to get laid, or someone who is very democratic.

Old Gregging 

(V.) To Old Gregg on someone is to hit on someone very creepily and awkwardly, usually in an attempt to get that person to do something he or she doesn't want to do but that you do.

Effective examples of old gregging include:

1. throwing out continuous strains of awkward, senseless questions, such as: "do you want to go to a club where people wee on each other?" or "do you ever drink baileys from a shoe?"

2. Do you want to see my mangina?

3. You got your rod stuck in my head motherlicka
