Dennis O'neil

THe coolest teacher in the universe. So awesome that 1/3 of his class dressed as him on a friday. Sometimes he will give us goldfish. He is the greatest Social studies teacher. He always has his pocket constitution and volleyball rulebook.

He is so cool, he must be a Dennis O'neil.

Quinn O'neill

This is the type of kid who hops the border back and forth in a daily basis with ease, while playing salsa music from a junky ass boom box on his back. This species of people also have a bad understanding of English, and often respond with "No quema cuh" when they are bamboozled. Typically when these people grow up they go through lots of no quema cuh trucks because they always crash them into curbs.

Aye bro that dude climbing the fence reminds me of Quinn O'Neill

The last name of a kid that is a fucking dumbum and a brat. He will most likely kill you if you make funny jokes about him or he will just tell on the whooolleeee classsssss.

Did you see that guy having a temper tantrum? Yeah he must be an O'neil

Robert O'Neill

The first time having sex with your girlfriend. You have meticulously planned every part of the event down to the most minute detail. It finally happens and it is executed with perfection, though your mind was hazy, and all you know is that it ended with a head shot.

I finally had sex with Trudie last night. It ended up being a Robert O'Neill, but it was great and I can't wait to do it again.
