Get the siobhanmug. Siobhan is a teenage/young adult heartthrob. She is cool and collected but underneath, a horse girl and a high key weirdo. She is multi talented and one of those annoying people who are good at everything. Typically, siobhan will have two hottie, baddie best friends; a fierce, Guinness loving gal who plays men's hearts and a loserly trilingual. Siobhan is funny and you can laugh at her. Only the 2 hotties know siobhan's real side.
Keith: "hey, is siobhan in the building?"
Troye: "Keith, you're always looking for Siobhan. I don't blame you though"
Troye: "Keith, you're always looking for Siobhan. I don't blame you though"
