Tag Up 

In the bases metaphor for hooking up with women... Tagging up is when you are at one base (such as 1st base, makingout) and you move to go for the next base (2nd- grabbing boob)... and you get denied by the girl. You then return to your original base and await for your next opportunity.

I was hooking up with Emma this weekend and i went for second and got denyed but luckily i was able to tag up.

Tag-Up 

Riding around on a BMX, looking fresh whilst wearing a paint mask with a rucksack on filled with Spray Paint.
Do this in a group of 8+, going out at 1am hitting up all the major visible parts of your city leaving your mark.

A “Tag-Up” ends in going to a party which is held on a field. Loud music, alcohol and drugs.
You will hear House, RnB and Rap music at these partys the DJ is normally a well known underground DJ, and it changes every time there is an event. The people who attend these partys are not all the type of people that go out on these "Tag-Up" events. They are just there for the music, alcohol and drugs.

Only one person is aloud to take pictures of the night, and that person is a trusted member of the group. All images go on to the private site so people can see. Images are not aloud to go public without permission.

You get randomly invited to these events after you have been vouched for by another member and you must attend at least 6 before you are given rights to join the group officially, and gain access to the website.

Lets go on a Tag-Up
Nahh, it's dangerous man. People get arrested all the time for it

Tag up on that! 

An expression used to claim ownership of something that is not and (potentially) never will be, yours, but is highly desirable. Examples may include a Ferrari, a super hot female, a mansion. Once something is "tagged up on", it cannot be tagged by a buddy, it is yours, forever...in fantasy land.

Dave: "Woah, check out the chick in the black bikini!"
Bob: "Yup, wow! Tag Up On That!"
Dave: "Aw, man! I was gonna ask her for her number too! Well, I guess she's yours now."

Hang-up tag

When you are ending a call with someone and neither of you can close the call and get the phone hung up. This can be uncomfortable and prolongs the call unecessarily.

Eric~"ok, well I'm gonna go now"
Alta~"ok, I hope you have a good night"
Eric~"I will. I hope you do too"
Alta~" I know I will, you too"
Eric~"ok, goodnight"
Alta~"sweet dreams"
Eric~"don't let the bedbugs bite"
Alta~"ok bye"
Eric~"Bye"
Alta~"bye"
Hang-up tag. Puke!

pop up tag 

A Pop up tag is a hashtag game on twitter that isn't scheduled. Somebody thinks of a hashtag they think is fun and post it on twitter, people that like the hashtag play along.

I'm not playing that hashtagroundup tag I don't like it. I'm going to play this pop up tag instead

Fartism (Updated Definition, Please Check Tag) 

A new-age philosophy that states that farts, in and of themselves give life meaning and happiness. In other words, this is a philosophy that attaches prime importance to farts over everything else and necessitates one who follows this philosophy to fart 5 times a day to give thanks/homage to farts, as well as eat beans every day in Ramadan to please the fart Gods, on a very sound epistemological foundation that farts clear out the waste (i.e. darkness of the human experience), therefore fartism is the thing that brings light to the entire world (by eliminating all the waste/bad of the universe) answers all the questions of human existence and more, and is supported by all other philosophies/religions in the entirety of the world's history (as well as is a fundamental truth of reality whose true nature is acknowledged in some way or form by all philosophies/religions in history, whether you realize it or not/ is intrinsically supported by/woven into the very fabric of existence itself).

David just subscribed to fartism (updated definition, please check tag) yesterday. He is now a born-again fartist who has understood all things and has achieved 100% enlightenment, unlike Spongebob in that one episode where he said "I know everything now", yet that wasn't true cuz well, his brain is limited. Fartism is not limited, however, it is true and explains all of reality/is a concrete reality, whether our brains understand this or not. Take that, false* religion.
