Get the Niamhmug. Literally the coolest person(s) on earth. Very funny and easy going until you mention something that isn't so alpha, then the attack you with their pack of hungry friends, often named Ana. They're very emo, and super duper hip. Niamh's can be located in dark, party-light lit rooms. They seem to always be wearing clown makeup, but when not they have a very bendable human like face. Niamh's are epic.
Me (super alpha), trying to make friends: Are you cool?
You, a beta: yes.
me (alpha): Not as cool as Niamh though
*you just fucking die LMAO*
