This is what you give your girlfriend or wife in order to find out if she's ticklish.
"Hey Joe! How do you find out of a girl is ticklish or not?"
"Give her a test-tickle"
"Ha, ha, ha, haaaa"
"ha, ha, ho, haaaaa, hooooo, ha"
"ha, ha, ha,ha"
The act of tickling a person who is either conscious or not, with your testicles.
She was sleeping on my couch so I thought I would wake her up with the Test-Tickle.
