The word coupon originated from the actions of a one person; Sean Daschko. So intense were the actions of Mr. Daschko's 'Coupon' methods that a definition was created to fit this unusual behavior. To be a 'Coupon', or to use 'Coupon Methods' is to effectively take advantage of your surroundings in order to enhance ones own private needs.

[Julian]

A physical or (more usually) conceptual or virtual token for the later provision of oral sex, given by a somewhat cheap person, to someone (usually a lover or spouse) who has just provided goods or services that cannot be immediately (physically or financially) reciprocated.
By constant use the term coupon itself comes to mean the thing for which it is a token, namely, oral sex.
Believed to be derived jointly from the prevalence of coupons in late post-industrial/[capitalist society] (largely exchangeable for low-quality [goos] - see [coupoff]) and from the Scots/Irish/Gaelic coupon meaning face - coupon/face then suggesting head or oral.

An alcoholic beverage and or container of hard liquor purchased sometimes days, but usually only hours before going to a bar, or going bar or [club hopping]. This alcohol is drank before going out, and sometimes drank while out, out of a flask, in the act of saving money on the bar tab but still keeping your [buzz up].
Some people even associate this coupon with the act of pregaming. Pretty much anything [dranken] while pregaming to any event could be considered a coupon.
