Someone who is perpetually on drugs and comes up to you on the street and is like, "...blah, blah, blah," for hours. All you try to do is get away but they keep yapping about bullshit that they make up. (I swear to you there is a drugtard at my door right now knocking and knocking away as I'm typing this). A lot of times they are your neighbors and you have to avoid them as much as possible because they will ask you for some stupid ass favor or make up some crisis because they have no jobs and nothing to do but be on drugs and addictive medication.
Most of the people who live in this apartment complex are students or drugtards. The drugtards are a pain in the ass.
