Well then.... That's a fascinating term
To be honest, I web-searched "plagiar-gargalesist" before I read the post.
(I was confused that it was an actual thing I shouldve known about before reading about it!
Lets see...... I know gargalesis means laughter-inducing tickling.
And "Plagiar"? I can only guess it means plagiarism. Lol
So... It means: Plagiar-Gargalesist: One who imagines themselves as a pop-culture character, taking part in a tickling-themed fantasy.
Lol, awesome.... I like it 🙂 Maybe it will catch on!
As far as words go; Knismolagania just sounds nicer than Gargalesis, or than "Gargalogania" would
Lol, the latter sounds like your throwing up.
But, linguistically, it makes more sense than Knismolagania does.
To answer your question: Yeah, I used to do this when I was younger.
(I'm a ticklee, so I'd imagine myself as a relatable character, being tickled )
this was before I even knew what this fetish was - I just thought I had some weird obsession with tickling. Lol. Which, is true regardless 😉
But ever since I joined the Fur Fandom, at age 15-16, I have since imagined myself being tickled as my Fursona. (I.E.;My own personal Anthro-character)
To this day, I still fantasize about my personal character in those situations;
*primarily because I'm an artist, and this helps me to imagine ideas for new drawings 😉
(However... This isn't really "plagiarism" though.)
~ Even though the Fursona is not "me", i made her to represent myself...
(New Term: Sona-Gargalesist) lol, 😀 !
Whenever I watch a tickling video, I imagine myself in the place of the Lee.
And the same goes for when i look at tickle-themed artwork, or images.
~~~ Could this also be what your asking about ??
Idk if Lers do something similar to this too, (because the focus of most tickle-themed content is typically on the Lee.)
