Refers to da ratio of how much your "upstairs" hangovers (i.e., "morning after" headaches, nausea, etc.) affect da flabby "hangover" --- i.e., floppily-drooping beer gut --- dat gradually develops "downstairs". Generally speaking it'll be about equal; in other words, da more alcohol you guzzle, da more of an "overhang" you'll get at your waistline.
Seeing other folks afflicted with an "upstairs vs. downstairs hangover" should be ample motivation to not start drinking yourself!

Downstairs energy just means that something is better than something else. Like when you are at a party the energy is always better either on the first floor or the basement.

A euphemism for jacking off. The man downstairs is referring to an individuals genitalia. By showing him who’s boss, you are beating him, aka beating off, aka jacking off.
Man, work has sucked today. I think I’m just gonna go home and end up showing the man downstairs who’s boss.

A women’s very tender juicy, scrumptious, wet, fishy environment near the lower side of their body. This alleyway is enjoyed by many men who are bold to enter it
