A "Kayak" is that person you see in public that makes you mad, laugh, and wonder what the fuck they are thinking all at the same time. That person you just cant seem to find the right word to describe. yeah, thats a fucking kayak.
that guy at the bar with the leather jacket tied around his waist, anyone that smokes fish, anyone with a mustache/mohawk combo, someone with a tattoo of a tear under their eye. "hey look at the fucking kayak", "that guy was a total fucking kayak"
