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.
