When you are dry humping i.e.- attempting to have sex while fully clothed, however, your clothing is wet. Thus no longer making it 'dry' humping.
And all of a sudden, we fell onto the shower floor, water running, and still fully clothed. It was pretty much dry humping, but our clothes got wet. So, I guess we were damp humping.
