hailjack
a person who is loud, smells bad, and won't let you leave
My cousin is a hailjack. He won't let me leave the party and smells like a cheeseburger that's been sitting in the sun.
That kid in my class is a hailjack. He talks so loud I can hear him from the other side of the school.
My neighbor is a hailjack. He smells like a gym sock and won't stop yelling at his dog.
