Laich
A super annoying way to tell someone to back off, like when your cousin is being a loudmouth at your grandma's house and you just want to rip their hair out.
My cousin said 'Laich' when I tried to eat the last slice of pizza.
My brother yelled 'Laich' when I spilled soda on his new shoes.
My friend said 'Laich' when I texted her 10 times in a row.
