Musquirt

The runny liquid substance that comes out of the mustard bottle before the actual mustard if you don't shake it well before use.

I went to put mustard on my hotdog and all I got was this fuckin musquirt.

Musquirt

The extra "mustard-water" that comes from a bottle of mustard when it's not properly shaken.

Person 1: "Dude my hotdog bun is ruined!"

Person 2: "why?"

Person 1: "Because, I forgot to shake up the mustard bottle and now my all-American-snack is completely soaked in musquirt!"........."Ewwwwwwwwwey!"
