Skrats can be easily recognised by the way the brag about things anyone else would find embarrassing: their hangovers/what they did when drunk/how many boyfriends they've had. Their everyday speech is somewhat incoherent and their typing is even worse(sexy_bich says: i heart u cuz ur leik da htst tng on da plnt!11! lol). They always, always, always idolise Christina Aguilera.
"Shut up, you little skrat- you're a living joke."
Can also be used as a verb.
"Skrat, your scheming level must drop before I pellet gun you"
"Skrat, stop bringing in meadow voles to our basement!"
"Stop skrating like a lindzoid
