This rare kanji has no clear standalone meaning. Treat its meaning as uncertain.
捴 combines 扌 (hand) with 忩, but the historical origin and original meaning are uncertain.
The hand radical 扌 beside 忩 suggests an action, but without a known meaning, picture a hand doing something vague with the shape on the right.
For フン, imagine a hand making a funny gesture: fun -> フン, though the meaning remains a mystery.
