The most unreliable, thick, fucking retarded person ever. Don’t get involved with a Siobhan. They’ve got issues.
Person 1: Siobhan punched me in maths.

Person 2: why?

Person 3: I spoke to her.

Get the Siobhan mug.
Siobhan can be a bit of a wet lettuce, a perfectionist. She can sometimes come across blunt, but she is very caring. She is however not as sympathetic as the others but she does have a heart of good. You will find Siobhan in MAU green/red. Do not give her the clipboard as she will end up bossing you around.

Siobhan licks ball balls for good luck, has a white ring around her mouth, has strict ass parents, lowkey kinda resembles a horse. She gives head every weekend for fun. She loves cow period and hangs with baby turds she loves the weekend because that means she can catch up with her fellow horse girls. She is great at being a sexc mofo.

Absolutely the most annoying and unreliable person ever. She is not worth your time and an absolute slut. Do not get involved with a Siobhan. They’re all spychopaths.
Did you see Siobhan?
Oh yeah she’s such a spychopath
