Louis Tomlinson is the latest member of 1D to acquire new ink.

It's not secret that the bros of One Direction's love them some permanent ink! And nope, we're not referring to a pink-colored Sharpie pen (although that would be an interesting twist) but rather, some mad permanent, forever-on-your-body-until-you're-wrinkly-and-97-years-old tattoos. And sure, 1D's Harry Styles might lead the tattoo brigade with the two huge swallows on his chest, the retro-looking ship on his arm, and whatever he got done during this inking session, but let's not forget Harry's 1D cohort Zayn Malik commemorated 1D's sold-out show with some ink of his own. Now, feel free to add Louis Tomlinson's brand-new tattoo, the words "The" and "Rogue" on each of his ankles, to your "1D Tattoo Watch Newsletter."

While we do totally fancy ourselves professional tattoo detectives (STILL trying to solve the mystery of Justin Bieber's owl tattoo though... And we will NEVER give up), we sadly have ZERO clue what the eff Louis' "The Rogue" tattoo means. What's more, Louis left it to his ladylove Eleanor Calder to Instagram his new ink out to the world and, um, there was no caption. That in mind, while we can't personally confirm, some fellow Tomlinson Stans say that The Rogue was actually the name of Louis' high school band. Or, perhaps it means that he feels like the badass "The Rogue" one in 1D? Hopefully, Louis will soon explain the ink's meaning, but until then, we have no problem fantasizing about how ADORABLE Louis must have looked playing in a rock band in the ninth grade!
