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.

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."
