"too stoned right now"
When one is too stoned on weed to do something that is asked of them, or even suggested to them. This can be the smallest or the greatest task imaginable, when one is too stoned right now, one is too stoned right now.
Person A: "Wuaow man, check out this crazy article I found about existentialism/music/twitter/plaster board/anything."
Person B, after smoking a considerable amount of weed: "tsrn"
Meaning: "I have an interest in when you're sending/showing me, but right now I can't do it, however at a later date I'd love to see what is it you want to share with me."
