Laddiebuck
A laddiebuck is a guy who is so average, he could be the boring part of a boring movie.
"You're a laddiebuck and you're gonna die alone.", said by your gym teacher after you failed a push-up test
"I'm not a laddiebuck, I'm a legend in the making.", said by a kid who forgot his lunch
"He's a laddiebuck who still believes in fairy tales.", said by your dad after you cry about a video game"
