Wet Willy. Or is it Wet Willie. I used to know a radio guy who's nickname was Wet Willie. But I digress. What kind of an adult gives his girlfriend a 'wet willy' and won't stop. For so long that she called Police and wanted him arrested on a domestic dispute charge. Grade school is over. And what would he say on his first day of prison when his cell mate asked him 'What's he in for?'
