Recyclables, similar to hoes - are people you hook up with repeatedly and regularly. Having recyclables is a more suitable option than having several one night stands as it increases your chance of having good sex and provides you with a sense of familiarity and stability.
However, in comparison to hoes, recyclable is a much less derogatory term. Recyclables are almost like a step down from friends with benefits. You have mutual respect for eachother and enjoy spending time together occasionally outside of sex, but the difference is the relationship is based on sex with friendship as a benefit.
