A nigga or a bitch that is down aka ride or die for what ever, when ever, how ever, for their significant other/lover or friends/potnas. When times hit rock bottom or don't go as planned they are down and willing to stick it out and make it through the rain.

Bottoms down means that you are done doing shots and do not want to end up with a six star hangover.
Annie's friends were taking shots one after another and Annie did not want to get involved, so she said bottoms down.
