This is a common olden saying that was said a lot back in the olden days. I think I heard someone say this one time awhile ago. You'd rather have a horse that could walk to the water, than two horse that'll cost me more in the long run.
Man that reminds me of the saying "I’d rather a good horse that’ll walk to the river, than have to buy 2 bad horses that will ultimately cost more in the long run"
Baddope can refer to drugs but also someone who’s Bad and you probably don’t want to associate with. Are known for for doing grimmy things. Usually have bad intentions or just no good.
Example:
Boy 1: "I’m gonna try to talk to Nay"
Boy 2: "Nah man don’t she bad dope I heard she be playing people"
