1. a mask or respirator for the nose only, allowing the mouth/tongue to be used for the servicing of presumably maloderous female genitalia. Mask is of the 'hose and bag', M42 or 'WWI' style as most protective filters are too large to be inserted in the nostrils. 2. (field expediant) a pair of BCG's (Wiley SG-1's) and two cigarette filters, field stripped, inserted in the nostrils. 3. a necessity when warming up a female for coitus who has been away from base camp (and soap/water) for 3 days plus...

Kristen: OMG! Do you have a mask boner?!
Mark: What’s that?
Kristen: When you have a stick in your mask making it look like your mouth has an erection.

Like hat hair, mask beard is the state a medium to large beard gets into when shaped by a tight or poorly fitting mask.
Bro that mask beard has ruined your carefully rugged exterior, and you now look like a poorly trimmed hedge

When the man is about to reach his climax, he stands on an object above the girl and rains his cum down on her, like a pigeon does with its poop on unsuspecting new yorkers. He then proceeds to flap his wings and tries to fly away.
Pigeon masking: Yo dude, I totally pigeon masked your girlfriend last night...she'll be washing the jizz out of her hair for weeks!
