When you
drop your
iPad (or whatever, don't get all Samsung-
hot-head on me now, we all know what the concept is here) on your face while in bed.
This is also interchangeable with phoneslap or podslap, whatever the case may be.
(Disclaimer: Careful how you use it, some of the below phrases could get you in trouble with the significant other.)
"Yo I totally got padslapped last
night while stalking your social media page"
"I took a serious padslapping in bed last night"
"Ooo. PadSlap!
Maybe next
time hold that pad with your dominant hand."
