San Antonio Mustard Packet 

When a female takes a bite out of a male's colostomy bag when it is full and lets it pour into her mouth.

He asked me if I wanted to know what a San Antonio Mustard Packet is, and then he ruined my good apron!

Pocketful of Mustard

UK slang: "I've got nothing." or "Nothing came of it."
I think it comes from something like 'couldn't even get a drink at the pub, just left with some stolen mustard pacs'.

Did you get the (job/girl/money/news)?... Nah; "pocketful of mustard."
