A wah wah
You throw this at someone who's too soft and cries at the drop of a hat. It's like giving a baby a slap and calling it a timeout.
'You're a wimp! A WAH-WAH!' she yelled at him after he got a B on his math test.
He called her a 'WAH-WAH' after she cried when her ice cream fell on the floor.
She threw him a 'WAH-WAH' after he said he was gonna die from a paper cut.
