Piggy-Bankin 

When you fuck a dirty, sluty, heavy set girl in the ass and stretch her O-ring out, then when you plop your cock out while her hole is fully stretched you quickly drop a coin in her ass crack and let it roll right in her donkey hole. Cha-Ching bling bling piggy bankin that BITCH.

Homegirl was so loose she had me straight piggy-bankin that ass.

Your mom is such a broke whore she's been piggy-bankin the whole block

piggy-backing 

This is a term used for the concept of when a person unenlightened about club drugs wants to buy ecstasy. Usually the dealer will give them something other than ecstasy that takes longer to create an affect. The uneducated person knows enough to know that ecstasy takes about half an hour to start working. So, once the drug doesnt work within half an hour they will go back to dealer to ask for another pill. The dealer will then give the person another pill of the same kind. This will then kill the person because little did they know that the drug they took was something much stronger (PMA or China White). One of these pills can kill you, let alone two. The dealer does not care because they made their money.

This whole act of taking one pill and then another right after because of not knowing better and a drug dealer not caring is pigg-backing

PMA - Even more powerful than Ecstasy. Takes a little longer to take effect. A CAT scan of somebody's brain because of use of this drug showed empty gaps in their brain.

China White - three pills that look the same as ecstasy and sold as ecstasy. Contains DOB, which is a very potent drug and can easily lead to overdose.

Kid(doesnt know much about ecstasy)
Dealer

Kid: u got any 'E'?
Dealer: Sure *holds out hand* pick one.
Dealer: Since u seem young I'm going to give you a break and give you 1 for 25. (really not giving kid a deal)
Kid: Thanks
Kid takes 'E' but takes a long time to
work
Kid: *goes back to dealer* this isn't working, do you think i can get another one?
Dealer: Sure

Later on, kid drops dead on the dance floor
