Originally an acronym for "pictures of people doing stupid stuff (or shit)", POPDSS evolved into "popdiss", and is now used to describe not only pictures of others, but also the act of taking said picture or "popdissing".

In either instance of usage, the act of taking a picture is key.
For instance, a person cannot be "popdissed" over the phone.

However, posting the photo on an online forum or blog is also a key part of usage.
This way, one could be "popdissed" over the phone, through picture messaging, or said online posting.
Greg got totally wasted at the party last night, and I popdissed him peeing in the sink. I'm putting it on my Facebook right now.
