A conceptual album and the second studio album released by Nine Inch Nails in May of 1994. It revolves around an unidentified man who basically goes on a "downward spiral" essentially, or path to eventual and imminent self-destruction.
It went quadruple platinum, and was deemed (I can't, for the life of me, remember who said this) "The bleakest platinum album probably ever released."

After ending a relationship, you proceed to have sex with as many partners as possible, often mitigating your regular standards in order to get laid. The spiral is often not acknowledged by the spiraller until he/she experiences coyote ugly.

The spiral you descend into, much like Alice when she was in Wonderland, where you keep falling and have no sense of time. It starts with watching a video of a cat that your friend sent you, clicking a related clip of a baby laughing, to ultimately watching an R rated clip. You then come to your senses and realise you've just wasted 2 hours of your life watching pointless videos and vow never to do that again.

Aviation slang for a situation in which a pilot unwittingly enters a gentle banking turn, ultimately ending up as a spiral dive to the floor. This typically happens to incompetent or inexperienced pilots unable to visually assess the aircraft’s position relative to the horizon. The strong impression of descent leads some pilots to disregard the flight instruments (which will show exactly what’s going on) and try to correct the situation by pulling up, which instead tightens the turn and often leads to certain death. This is extrapolated to situations where a person will stubbornly press on with something extremely stupid despite solid, objective reasons not to.

A shame spiral characterizes the loss of self-control over something that makes one feel worthless and pathetic. Due to these feelings of low self-worth and guilt, the action that triggered the shame spiral is repeated and the degradation of one's self continues. It is a cycle that repeats itself, bringing one down further as it repeats. Example triggers for shame spirals could be excesses of junk food, alcohol, meaningless sex, buying unnecessary gifts for oneself and the like.

The act of continually lowering your standards so that each new sexual partner is worse than the last.
