A taco that isn't shaped like a taco. It has taco ingredients. It tastes like a fantastic taco. However it does not operate like a taco. Folded like an envelope (yes people still send mail the old fashioned way) you open it into taco EEeeeectsasy...welcome to flavour country my friends:)

Open your flavor envelope and cure your hunger. You are hangry and bitchy.

Manila Envelope 

An ideal vessel for the dignified and impactful delivery of one's feces to an enemy. It must have a button and string clasp so that the recipient is held in suspense longer, anticipating the contents.

I will watch and count each time he slowly, curiously unwinds that manila envelope string. One, two, there's my poo!

I sent my ex's lawyer an anonymous manila envelope of my best wishes.

I'll slice you open like an envelope 

Used commonly by football hooligans, 'I'll slice you open like an envelope' can hint that the person saying the phrase is carrying a knife and intends to use it lethally on the person they are saying the phrase too. Can also mean that the person it's being said too acts 'big' and 'untouchable' and the person saying it is easily going to beat them up.

'Threat'

Football hooligan- 'you think you can take me on?'
