Fellatiostomy is the act of fellatio provided by a person who has a tracheostomy. The benefit of a fellatiostomy is that the "giver" does not ever need to stop to breath. The danger is associated with "ball-valving" where the scrotum intermittently obstructs the tracheostomy causing suffocation.
I had the best BJ last night because the chick had a fellatiostomy!
