A rare STD. It originated from inbreeding in Pine Bluff, Arkansas. Symptoms can include mental retardation, loud-mouthness, social retardation, blisters, uncontrollable annoying singing, sister-banging, and frequent urination. There are possibly more symptoms that will be found in further studies. If you come in contact with a carrier of Ives, be advised that there is no known cure. If you believe you have been infected, save your friends and loved ones and become a hermit.
Waitress: "Your accent sounds fake"

Ives infected person (while showing ridiculous Pine Bluff bicep tattoos): "Girl, I'm from PINE BLUFF!!!!!"

Innocent bystander: "Dude, I think he has the Ives"

IVS stands for itchy vagina syndrome. Some days your just itchy down there, it could be a disease or because you just haven't shaved in a few days but whatever the reason you just can't stop touching your vagina.

IV (abbreviation for Initial Value) in Pokemon video games (blue, emerald, diamond, etc.) - IVs are randomly generated numbers that give individual Pokemon a bonus from 1-31 in each stat. These are set bonuses that are unchangeable from the time the Pokemon is born or first seen in the wild.
Not all Pokemon are created equal. My Pikachu is better than yours because he was born with a 31 IV in speed and special attack.
