Boner Narcolepsy
A boner so strong that it drains the blood from your brain and causes you to faint
We saw a nice piece of ass walk by and Tim fainted from Boner Narcolepsy. I had no idea he had that strong a dong.
Boner narcolepsy
When you pretend to be asleep because you don't want your roommate to think you are checking out his raging boner.
Pretending to be asleep (lapsing into classic Boner Narcolepsy) , I kept my eyes closed and lay perfectly still while Stephano pranced about our dorm room with a massive boner.
