Google Seppuku 

"You use a Japanese text input tool and enter random Japanese characters into a google image search.

Then you count how many pages until you find an image so disturbing that you wish you never played the game."

"JESUS CHRIST!! What? Oh sorry. Not you. I was playing google seppuku and I lost. I lost big time."

Pa' que sepas 

Shortened version of "para que sepas", which means "so that you know" in English. May also be heard as "pa que sepa" in places like the Dominican Republic where "s" isn't really pronounced.

Loose English slang translations could include "for your information" or "you know it!"

Example: I rep Puerto Rico all day, pa' que sepas!
I rep Puerto Rico all day, so that you know (/for your information/you know it)!

Sepp Blattered 

To get unbelievably drunk. So drunk you make awful decisions, mostly for the benefit of yourself and no-one else causing utter turmoil to many people around you. You will become a complete and utter arsehole, talking about topics you have no knowledge or passion about.

Guy 1: "What you up to tomorrow night"
Guy 2: "Mate I'm getting Sepp Blattered... Christ I don't expect to see tomorrow"

Beard Seppuku

When a man attempts to trim up or style his beard and makes a fatal error, forcing him to go clean shaven rather than bear the shame of failure.

Seppuku is the custom of Japanese samurai to commit ritual suicide upon suffering great dishonor or failure.

Pierre: "Hey dude, why'd you go clean shaven?"
Antoine: "Ah.. well, I made a mistake while trimming and had to commit beard seppuku."
