gargalesis
Heavy tickling often leading to laughter.
uncountable
Pending a better nomenclature we suggest for the former the term knismesis and for the latter the term gargalesis, with the adjectives knismic and gargalic, hyperknismesis and hyper-gargalesis for excess, etc.
Where it comes from
From Ancient Greek γαργαλίζω (gargalízō, “tickle”) + -esis.
