A concept outside America that is used commonly as a slogan among enviromentalists, some politicians and the like. Recycling is when someone takes used paper, tin cans, milk jugs and the like to a recycling bin so it can be cruched down by machines to be a new product. However a few of the posters here tend to use it as a sex term. And oh a decent source of cash if you need that few extra cents.
The act of hooking up with previous sexual partners and/or previous significant others in order to prevent your number from becoming higher and maintaing an appearance of strong morals instead of low standards/values. Although you may be infested with STDs nonetheless.
If you're having a dry spell but don't want to take a chance on a new partner, just call up an ex and recycle.
When two people lie side-by-side, laying in oppositedirections with their backs arched and facing each other. At this point it is possible for each partner to defecate into the mouth of the other partner where they can consume it simultaneously.
