For years, scholars have pored over the lyrics to Sisqó’s 1999 smash “Thong Song,” debating the exact meaning of the Dru Hill singer’s repeated insistence that “she had dumps like a truck.” The leading school of thought is that it’s synonymous with “junk in the trunk,” while a small but dedicated faction argues that it’s more scatological in nature. And now, thanks to one intrepid journalist over at The Huffington Post, the mystery has finally been solved.

In a new interview, Sisqó confirms that the line is not about pooping. “That would mean I was some kind of fecal freak,” he says. “What I was really referring to was — a dump truck when it backs up, it’s like, ‘beep, beep beep.’ So, ‘she had dumps like a dump truck’ is, like, when girls do a booty dance move and they look back at their butt. She’s like a dump truck back-back-backing it up.” To be honest, Sisqó, that doesn’t really make much sense. But we’ll go with it!

In the same interview, the singer also reveals some of the musical inspiration behind his classic ode to women’s underwear. Some say that a sample of Wes Montgomery’s cover of the Beatles’ “Eleanor Rigby” is hidden within “Thong Song,” but Sisqo says that that song served only as a jumping-off point. Jackson owned the rights to the Beatles’ catalog at the time, and as Sisqó explains, “I’m a big fan of the late, great Michael Jackson but I wasn’t trying to pay him royalties on my song!” According to Sisqó, the track also contains nods to the Star Wars theme song and Nikolai Rimsky-Korsakov’s “The Flight of The Bumblebee” — “We got to put some of that in there, but not too much, so it’s not like plagiarism,” he says. I’m not sure that’s how it works, Sisqó, but OK!

I’ll leave you with one last revelation from the interview: Sisqó eats exactly one meal a day, on a square plate. “You can’t normally get a square plate on the road,” he says. “When I’m home, I have a real meal with a real knife and a real fork and a square plate.” Livin’ the dream, Sisqó!
