A hard-on produced or facilitated by Viagra, or any other such prescription drug for "erectile dysfunction." Viagr-ons are different from naturally-occurring erections in that they are more easily attained and don't require the same amount of genuine sexual stimulation. Also, they tend to last longer and throb more intensely.
I wasn't really into (her/him), but I had a total Viagr-on, so I figured, "What the Hell?"
