In the sense of creating laugh.
Not a fan I very much dislike it. I used to not be able to control myself but after many years of people exploiting my weakness I can now withstand it and be in control for a solid 10s I use that 10s to attack the person tickling me.
AAAAAAARGH!
Debbie Kuhn, is that you?
I’m not responsible for your broken face.
It’s something many people take too far/do too long. A quick tickle on the side or something is a cutesy playful thing to do. Tickling every chance you get, or tickling for a long time is obnoxious. Someone shouldn’t have to yell or smack you to get you to stop.
