look up any word, like bukkake:
 
1.
An activity commmon in prison,where an inmate poses of in the nude,usually showing his bare ass even with the cheeks parted so another inmate can take in the view,whilst pleasuring himself.No physical contact is allowed.Hence the photo connotation.
one inmate to another,"i'll give you half a cigarette if you give me a "donkey photo"."
