When you're smoking a joint or blunt and you hit it enough to keep the cherry lit but not to much so the paper doesnt burn and only makes smoke when you hit it
Jeremey: "yo dawg you smokin' a J?"
Ricky: "yeah man but that shits on the low so we can't be cheifing on it"
An individual, particularly a female, who is not worthy of being the company of the opposite sex during the daylight hours. One that is fine to spend time with behind closed doors where nobody can see, rather than outside in the public view of others.
Boy: Baby last night was fun.
Girl: Yea it was and I was thinking maybe you should meet my par...
Boy: Whoa!!!!!
Boy: I can't be seen with you! That would ruin my rep! Then I would be labeled as "that guy who's fucking the fat bitch."
Girl: I thought I was your Lover! WE'RE SOULMATES!!!!
Boy: Some would call you a "practice girl" BUT I would just call you a...how should I say this....OH! an "ON THE LOW" HOE !
A female whom a gentleman hangs/hooks up with frequently, but keeps a secret from all but his closest friends. Often a distraction from a long-term relationship that can't fufill said gentleman's specific needs.
A hoe on the low is either a male/female who is secretly a hoe. Not a lot of people know about this "hoe" because they keep their hoe-ish ways on the low. The "low" is basically abbreviated as the down-low, which means they keep it to a point where people don't know about.
Girl: You see that boy over there, dude is a hoe on the low.
Girl 2: For real girl? He doesn't look like he is one though.
