a maw
Maw is a Scottish word for mom, but it's also like when you're too lazy to explain why you're mad, so you just yell 'Aye, yer maw!' and strut off like you're the king of the world.
'Why are you ignoring me?' 'Aye, yer maw!'
'You didn't invite me to the party!' 'Aye, yer maw!'
'You ate my sandwich!' 'Aye, yer maw!'
