He's so nasty
You know, because he's such a menace.
Maybe he's being threatened by Niall 'da pimp is here' Horan so has chosen to up his BadBoy game a bit. Maybe he'll be busting out all kinds of intimidating sounding raps on the next One direction album.
Mmaybe he's just really, really angry with Florida.
Either way, he teamed his tee with a baseball cap perched just-so on top of his quiff, a skateboard and a watch bigger than our face. Very all-American.
