Siv HD 

Robbert van Eijndhoven, a league of legends streamer who is famous for his generally humorous youtube videos featuring adc leblanc, ap miss fortune, counter counter-bruiser lux, among others. He has a sexy haircut and a voice that makes the angels envious.
He also raised well over $1million for Save the Children foundation in a single day of streaming LoL with over 7500 donations from his viewers. The donations reached $105,000, but the USAID multiplier for the fundraiser made it over $1million.

Siv Classic

When you get cockblocked by a friend because they get way too drunk, throw up everywhere and you have to take care of them.

Mike: Last night that girl was all over me, but David was throwing up everywhere and I had to take care of him.

Carl: Now that's a Siv Classic!

Credit Siv 

someone who does no work but takes all of the credit, someone who uses "we" when it comes to work she wants you to do, but sits and takes all of the credit herself for the work that you did. Someone who doesnt talk to you for 2 days if you dont do 110% of her work. Someone who acts stressed out and screams and swears to act like shes busy so no one bothers her. someone who leaves work early all of the time. someone whos time off grows interest.

Crazy Eye is SUCH a lazy credit siv, she needs to retire.
