The point of no return theory is when you take a member of the opposite sex (usually female) home to have sexual relations/fellatio. As you take off your clothing, she realizes that you have a tiny penis and/or a beer belly, but since you have already gotten to this point she might as well hook up with you--hence the point of no return. Essentially, a common bond amongst the ugly people of America where hope is found.

whenever there's "the point of no return" there is no chance and there is no turning back from a decision you are going to make
person 1: i'm gonna drink 9 bottles of beer
person 2: do that shit and you'll go to the point of no return
