Penny Stack

The penny stack is an amusement for people of all ages, get a load of pennies (or two p's whatever your choice) and get some some super glue.

Next stick one down on somewhere people will see it, and wait until dry. And then add another. Keep going until you feel satisfied.

Now someone will be very perplexed by the stacked up pennies. =

Did you see that awesome 1000 high penny stack?

Yeah dude, it was sick.

purple stack

A stack or wad of 500 euro notes.

It's called a purple stack because the 500 euro note is purple. 500 euro notes are the most widely available high-denomination currency, worth about 6-7 times a 100 USD note. This enables one to carry a lot of money in a very small volume.

Muhammad got caught flying out of Madrid with a million euro in purple stacks.

strong stack

In poker, especially Hold 'Em, the act of betting an obscenely large amount of money on a bluff, in order to force your opponent to back down. We made this up a couple months ago to mess with this kid who said he was a rounder.

Aww man, are you gonna let him strong stack you like that?
