DSM 

The DSM is a gang that was originally created to combat the A-TONY, but was unsuccessful. DSM stands for ‘Down Syndrome Massive’ and now after it’s defeat by the A-TONY, the DSM now focuses it’s attention on mocking people with both mental and physical disabilities; even though all the members of this group…have at least one disability of this kind.

"Man those DSM members really are a big fucking bunch of spastic twats, specially that botty"

Making a geek/loser in a full nelson and make them imitate the sucking their own dick.

When you put someone in a full nelson you basically break their back by making them look like their suckin their own johnson. Makes the dork feel like a pussy and a clown do it to a annoying ass kid at school and you'll be sure to get a laugh and definitely some respect.

Also make sure you yell out DSM, DSM, DSM while your doing it.

Dirty Sexy Money, the American drama set in New York City. It's about the Darlings, who are really rich. It came to E4 in England in 2008.

"Hey! You watching DSM tonight? Karen's gonna try to steal Nick off Lisa!"
"Hell yes!"

Q: What do you get when you combine the lowest quality American carmaker (Chrysler/Mopar) with the lowest quality Japanese carmaker (Mitsubishi)? A: An over-styled, unreliable, fast-depreciating sled. Diamond Star Motors is no more. Maybe Mercedes can help Chrysler actually improve the function of their cars instead of just the garish styling.

Isn't it strange that I know at least 7 girls I went to high school with drove Mitsubishi Eclipses, but none of them lasted 100K miles? Oh, well. Some Japanese decals will add at least 150hp. Try that with a Chevy!

See dreaded single male.

There's a reason why DSMs have a bad reputation.
