The Smoking Gun unearthed a federal search warrant application from the Department of Homeland Security, which decoded such confusing sexual codes as "BBBJ" and "Greek."

We're glad the guys in government have stumbled upon the meaning of some of these terms in their quest to bust illicit-prostitution Web sites like the one this warrant was issued for, but we couldn't help but notice some gaps in their knowledge.

After the jump, read more sex codes the DHS hasn't found out about yet.

GFE: Girlfriend Experience, aka an intimate encounter with kissing that resembles the kind of sex you would have with a date or girlfriend. They even made a movie about this one -- guess the DHS doesn't get out to the cinema much.

Roses: Dollars, as in "I will give you 100 roses for a BBBJ in my car." We can understand why the DHS doesn't know about this one yet; it's very confusing and difficult to decipher.

Water sports: This one sounds like it's about an exciting game of polo, but it's actually about peeing on each other. This could be a disaster for the DHS if they got confused.

NSA: No strings attached, aka the best acronym ever.

Non-pro: Someone who will have sex with you for money. Yeah, we don't get it either.

Ski, Tina, 420: OK, these aren't actually sexy but the DHS must be pretty confused if they don't know these acronyms mean cocaine, meth and marijuana respectively.

generou$: This was just a nice adjective until somebody replaced that "s" with a dollar sign. Now it means you are really generous about giving money to people who will put their mouth on your genitals.

BBW: An attractive woman of the larger variety (in this context, probably willing to put her mouth on your genitals).
