Raindrops

[Rihanna]

Slang for liquid LSD (acid), often combined with marijuana. Liquid LSD is stored in glass vials, and [dosed out] using an [eyedropper] ([raindrops]). It is much more expensive to acquire a vial of liquid LSD than typical street acid, which is usually laid on blotter paper (a.k.a. acid tab) and eaten.
