Sleeko

A man who is sleek and name rhymes with Sleeko. So pretty much anyone with a name ending in o. Kinda.

Nico is a sleeko because... well he is just himself.

Sleebomb

The repeated act of showing up late in an online discussion, saying something highly intelligent and articulate, and thereby ending all serious discussion afterwards.

We were all arguing about Israel and Palestine and then Timmy came in and sleebombed the entire thread with this really insightful observation.

Steelo

Steelo is a simple slang term meaning "style." The word "Steelo" w was popularized by urban youth in the NYC area in the early 1990s. As such, several hip hop artists Incorporated the use of the word, "steelo," in their songs. It flowed South from NY, thru Virginia, the Carolinas and the dirty South states of Georgia, Alabama, Mississippi, Louisiana and even Florida. It came to the US West coast after that and began to fizzle once the word crossed into mainstream after having been used prominently by the female singing group from that period that called their group simply "702". Now, it was rare to hear that word used past 1998 to present day, October 14, 2018. If you're STILL using "Steelo" in your vocabulary, you should stop... Immediately!!

You sound old and crazy!! Hope that this helps you guys out in the UD universe!

Hey girl, you see that sexy brother crossing the street? I love his walk, his clothes... I'm digging his steelo. Imma go and try to get his attention, be right back!!

Sleepover

What you tell your parents you’re going to do when you’re actually going to be pissed on some field and trowing your guts up from drinking too much WKD or Smirnoff.

Child: “Mum I’m off to a sleepover at Dan’s house, I’ll be back in the morning.”

Mum: “Ok, have fun.”

Child: *Smirks*
