Kryptonite is the new beer. It is a high energy, high alcohol drink with distinctive affects; namely memory loss, intense energy, false confidence and a guaranteed crazy adventure.

Designed originally for special occasions, but rapidly becoming a weekly, if not daily, ritual by students everywhere.

Kryptoingredients:

1) Red bull equivalent energy drink (Cheap brands - preferably "Red Rooster")
2) Blue WKD equivalent (Cheap brands - preferably "VS")
3) Vodka (Cheap brands - preferably "Morinov")

Depending on next day memory requirement, ratios can vary from 3:2:1 (I have an exam tomorrow), 2:2:1 (standard), or 1:1:1 (not for the inexperienced)

Pre-drinking ritual:
Once enough drinks have been mixed for all involved in the kryptosession, everyone must lift their glasses, clink them together, and recite the Kryptoast:

"See you tomorrow!"

An immense concoction, not for the inexperienced.
1) Mike: "Hurry up and mix that drink! I need my krypto!"
Sam: "But it's only 9:30 on a monday morning"
Gareth: "Yea but we is soled. Gotta hit the kryptosesh hard"

2) Mike: "Ahh mate i'm buzzing from that kryptonite!"
Sam: "I don't understand what you are saying my friend, I have had 4 pints of kryptonite"
Gareth: "Mix up some more biatch"

3) Mike: "Arhhh mann, I is buzzzinnnnn!!!"
Sam: "WOOOOOOOOOOOOOOOOOOOOOO"
Gareth: "fjdisdfojsifoijoisf!!!"
