The event that takes place after a jog.  Whichever event it may be, sitting on a curb, walking around, or eating a yummy sandwich.  One may only attend an afterjog if he/she attended the jog, or it is not technically an afterjog. 

Afterjog was a word made up by a teenage boy named peter when he was cross about not being invited to "hang out" at someone's house.  The event took place after a jog he was not invited on because he is slow...like...really...slow.  He asked, "...why wasn't I invited to the afterjog?" 
We laughed and made this a thing
The End.
