Welk boi is someone that lives in Immingham. He is highly intelligent but often comes out with stupid things without thinking, possible because his brain is overloaded with other things ;)
Often accompanied with the word loltard i.e - loltard welk boi!
ie - a welk boi would say - "You've tripped on mushrooms? Why would you trip over mushrooms?"
