Down low 

Back in the 60's, passing a joint within view of outsiders got the response: "Keep it low", or "Keep it down low (when you pass it)". This usually happened when riding in a car with friends. Over the years "Down low", "Keep it down low" and "Keep it on the down low" generalized into meaning 'keep it secret' or 'don't be obvious'.

(Old School version):
"Hey, keep it low!"
"Huh?"
"Pass it low!"
"(Puzzled)"
(Laughter from everyone else)
"Keep it down low when you pass it so nobody else can see what you're doing (you dummy)!"
"(Nods head "OK")"

Down bad 

The phrase virgins started using after "simp" was considered lame. They will call any man this phrase for even the slightest action of flirting with a female, because they themselves can't get a girlfriend. It basically means someone who would do anything for a girl to get their attention.

Guy- Damn girl you look good in that outfit!

Girl- Thank you!
Virgin to guy- Down bad (or astronomically)
