One Direction's Niall Horan shows off his (very muscular) side boob!

To all y'all who thought that side boob was for ladies only, check out this photo of One Direction's Niall Horan serving some stellar SB! (That's the new side boob acronym we're starting, tell all your friends.) Niall's visible pecs only prove that side boob is a phenomenon both men and women can enjoy, and it also allows us to announce the (unofficial) royal court of side boob: Miley Cyrus is queen and Niall is king (although maybe Miley would prefer Harry Styles?). Now, please pay your respects by wearing your own slightly revealing sleeveless shirt.

The "One Way Or Another" singer was snapped showing off his SB (See? It's so catchy!) in Dublin as he arrived to One Direction's concert. While some of you might be ecstatic that the chest-exposing trend is getting more gender-neutral, and you have every intention of referencing it in your next Gender Studies 101 paper, we imagine that the majority of you are feeling SUPER sad the Comic Relief spokesperson didn't just go shirtless and be done with it! Lucky for you, we searched through our archives to find this photo of Niall shirtless to tide you over! See? Research can be fun!
