An imaginary boyfriend made up by a completely insane 15 year old questionably female individual. Kevin is from a family of 6-12 children, all of which are boys, and he has/had an indentical twin brother who commited suicide.
Kevin can also be used as an exclamation when something is completely rediculous or fake.
"That chick's boobs are so fake."
"Yeah, Kevin Kristopher Kruise is realer than those."
