Where do I start! He’s the best boyfriend a girl (or guy) could ask for. So amazing to be around & will always make you laugh. Tall, handsome, too small for his own good and cheeky as hell. Those locks & blue-grey eyes, my gawd, how could you not fall in love! Killian’s also loves the Mary Jane so if you offer a Killian a joint, you gonna be his bestie. That’s if you’re lucky to meet one. You may know a similar being with a ‘C’, but those fellas ain’t shit, you need the Killian with the ‘K’. And hold onto him tight
Woooahh dudes, that Killian was fucking dope. Did anyone get his number ?

This person is very hot and seggc. Killian is mostly known for their aggressive and playful personality. Most people find them annoying and manipulative but if you get to know a Killian, you'll find that they're actually not that bad! (Even if they pretend to be). Killian is also known to be a liar but they can't really control it because it comes naturally to them.
Ligma: did you see that super seggc mf that just passed by?

Balls: oh yeah that's Killian, they're so hot...NO HOMO THO 😨
