The period of time after a man has ejaculated where (for once) sex and women aren't on his mind and he suddenly has a clear thought process bringing in major epiphanies and supreme moments of clarity on life;
fyi: (these "PERVs" only last about a couple of minutes, or even seconds, which then after the idea of sex returns back to the brain.)
So after his girlfriend fell asleep, Alexander went to the outhouse in order to blow his load before going to bed. With his lack of communication skills still on his mind, he busted his nut which brought on a Post-Ejaculation Revelation:
"If I could have somehow communicated with my girlfriend from another location over some talking device... I could have gotten sex tonight! Yes, this idea is grand! I'll call it the telephone!"
The rest is history.
