to like your own post on social networking sites such as Facebook. Sometimes people feel bad when their posts are not liked by any of their friends on facebook. hence they start liking their own posts. and his is how postabation works ... just like masturbation works for boys.
Hey no one likes my post on FB... i should postabate ....
When you recently get talking to a super hot chick on blackberry pin and you decide to masturbate, could be after receiving some invited messages or even a pic
Dude "i got this hot girls blackberry pin last night, couldn't wait to reserve any filth from her so i jerked off over her profile pic, some serious pinstabating"
