Manilla Envelope 

Someone incredibly dull and boring who has very 'safe' tastes and no personality.

"John is so lame..."
-"Yea, that guy is a manilla envelope."

Manila Envelope 

When a man is with two Filipino women, one of whom is giving him fellatio while the other gives him analingus.

I went to the Philippines and hooked up with two locals who gave me a Manila Envelope.

Manilla Enveloping 

When one makes the vagina wet and uses the "juices" to seal a Manilla Envelope and mail a letter to his Grandmother.

On Phone after Manilla Enveloping:
Grandma: Thank you for the letter Jonny, but why does it smell like fish?
Jonny: It went through France and Lindsey says your welcome.

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.
