Kerching-ing is when you paint your dick gold, then have sex with a girl. When you're about to cum, pull out, jizz on her face, throw a load of Monopoly money at her and shout "KER-CHING!".

Also known as a dirty millionaire, or a million dollar sticky.
"Dude, I was totally kerching-ing that girl at the party last night!"

"No wonder she isn't talking to you."
