To cut the sleeves off of a t-shirt, invented by Chachi, thus raising your cool factor by several points.
I was going to throw that old t-shirt away but I decided to chachinate it instead so I can look super cool.
Dude, you totally chachinated that shirt - I wish I was as cool as you!

Fucking off, douching out, keeping folks waiting, because their tanning bed, blow dryer, or other chach instruments isnt performing as it should, especially if drugs are involved...

See chachkies . The act of rummaging through old trinkets or figurines with the intent to purchase or collect, in order to clutter or horde and cover a large area on a small place.
Granny went chachin' today and came back with her Buick full of useless yet captivating ceramic cat figurines.
