The amount of time it takes a nerd to become useless at a nerdbang. Once this happens the nerd sluts move on to the next nerd, hoping that one of them can can quench their thirst for a satisfying nerdgasm.
Did you have fun at the nerdbang?
Fuck no, every single nerd lasted 27 seconds and I got no pleasure. Thankfully i had a #5 foamer or the whole night would have been wasted.
