(Similar to the term "Average Joe" but different in meaning.)
Someone who appears to be normal or average but has very unusual fetishes and secrets.
"Average Tim" over there looks pretty plain but the other night he was sucking a black dildo covered in pop rocks with the words "cock boy" and "knob gobbler" written on his chest while 15 people watched.
