I think it's a made up word because I could not find it's meaning when I
searched for it online. It seems like an onomatopoeia.

The only thing that comes close is an
[article](https://headlines.yahoo.co.jp/hl?a=20190722-00000066-dal-spo) about
a Japanese basketball player who entered the NBA




ちんちんかく means 正座をする(sitting straight) in Toyama dialect. However you had better
not use it except in Toyama prefecture, because most Japanese people would
think it means "to scratch a penis".
