Capping 

This word growing up in the 90’s meant like you were joking with someone.
Like telling a joke in a way of making fun of someone or something they do.

“You’re pretty short for an adult. Haha I’m just capping on you, you’re not that short.”

Capping stacks 

The art of putting larger chip denominations on top of smaller stacks to make it appear that you have more chips in a poker game than you actually do.
This is done by placing your hands around your chips so others at the table are deceived...

Using a cell phone to hide chip amounts
