Where a female first takes a shit before sex and doesn't wipe (most likely will be used as a joke). If the female is then being eaten out while she is on her hands and knees, the male's nose will be covered in the woman's un-wipped shit.
Man: So, my wife brown nosed me the other day.

Man's Friend: Really? How'd it go?

Man: It SUCKED!! I don't know what possessed her to do that! It was disgusting!

(Man's friend laughs as he nonchalantly texts everyone he know's about it)

The brown-nose or act of brown-nosing is also when a person removes their pants and underwear and climbs over a sleeping person so that their asshole is approximately 3 inches away from the sleeping person's face. The person performing the act punches the sleeping person in the stomach as hard as possible to wake them up. In theory, the sudden shock of being woken by the punch will cause the sleeper's head to come up and forward, thrusting their nose into the other's ass.

For added 'flavor', the person initiating the act may choose not to wipe after their last bowel movement at which point the act of ''brown-nosing'' can be referred to as the Mexican alarm clock or Sanchez's wakeup call.
1.) Hey lets brown-nose tony

2.) Last night we woke Ryan up with a Mexican Alarm Clock, he was none too pleased!

3.) When Sanchez calls, you have no choice but to answer!
