Lucas Barreto, 25, gets naked (Work Unfriendly) and puts a jockstrap to the test like Inspector 12 on a pair of Hanes. 

See Lucas's bare assets at Boy Culture's very, very inappropriate Tumblr.

And we thought Dwight Twilley's "Girls" was racy back in the day! Check out Del (Del Marquis of Scissor Sisters) & Xavier's campy, sexy, disgusting, surprising music video for "Let Me Tickle Your Fancy," which is very much Work Unfriendly.

Colby Melvin took the blogosphere by storm this year with his charming personality, good looks and, well, because his ass looks real good in a pair of briefs. Because we seemingly have nothing else to do over here at The Underwear Expert, we decided to take the California-based southern boy's greatest shots and give them some holiday "spirit."Ever wanted to see Colby as a submissive elf? Naughty Santa? Holy relic? Now's your chance! And here you were thinking you were too naughty to get presents this year. Check out the pics in the gallery above, and click here for more Colby Melvin than you know what to do with.

 

The third in a series of articles from The Underwear Expert...

Chord Overstreet has been bringing all the boys to the yard with his milkshake since his very first episode on Glee, the show that's the best thing to happen to people who like to watch adults act like teenagers since, like ever.

We saw him plunge into skin-tight, package-enhancing booty shorts for the Rocky Horror episode.

He dropped trou on Ellen’s talk show to reveal orange underwear that said "Ellen’s Got My Tight End Covered." (Because she so does.)

He got us wet when he showered for the camera.

Okay—you get the point.

Now, though, in the December 22, 2012, episode of Glee, the twentysomething Nashville native has offered his creamiest milkshake ever. Mocking Bane from The Dark Knight Rises, Overstreet runs around the McKinley High locker room with a jockstrap on his head. We won’t put thoughts in your head, but damn. Rarely has a jockstrap looked this fashionable tasty.

The adult obsession with sexualizing not-quite-yet-adults continues in Andrew Christian's latest upload, "After School Special." The cast of nearly naked characters is made up of horny jocks who get hazed and remain unfazed. Click here—Work Unfriendly.

The NFL's new Nike pants make X-ray specs unnecessary. Gulp!

College football player Vinnie Sunseri gave his fans a show when he decided to don a black jockstrap under his white pants. Thank God for sweat. More here.
