Holden, Chill.

"'Holden, Chill.' - Joshua, Luca, and Cosmo whenever Holden Zane Vest gets triggered"

Origin
"Josh Chill" or "dude just chill out" were popular phrases in Holbinski's vocabulary whenever he was playing with Joshua Edwards. Unfortunately, Holden quickly became the subject of his own meme when he developed a quick-trigger finger.
