Stank is an adjective that designates the emitter of either a stink or a stench. A stench is one magnitude more offensive than a stink. For example a stink: dog breath, and a stench: deep fajita fart. Stenches also tend to linger longer than stinks, like if you return to your car after shopping and it still smells of the fart you did earlier. With few exceptions, stenches are almost always emitted by human hygienic negligence or malfeasance whereas stinks are usually natural decomposition processes. The Chinese food that hits you like a shovel when you open the fridge door is technically a stink. If you leave it in there long enough and at one point need to open all the windows in the house, then it has traversed the boundary into a stench. So in summary something (or someone) that is *stank* is emitting either a stink or a stench depending on the reason and intent. Note that squarely 2 levels below stench on the offensiveness scale is a *funk*. A funk is the larval stage of a stench; usually the first subtle indication of a lapse in hygiene. Since self-funks are commonly encountered, more often than others’ full blown stenches, funks found on loved ones can often be misconstrued as disgusting yet somehow delicious, and tolerated if not outright appreciated. An example of this is the oft cited allure of a person’s funky armpit musk. Sitting in the offensiveness gap between a funk and a stench is *ripeness*. To be ripe is to carry more pungency than a funk but not yet produce the lingering qualities of a full blown stench. An example would be your coworker who eschews deodorant, or the guy down the hall who comes in every morning with laser breath because he survives on garlic bagels. In these cases proximity slaps you hard, with no allure of a funk but as long as they stay a few feet away they can be tolerated.
