The act of smoking a blunt overall. This involves buying not only the bag of weed(normally a dub or 20 dollars worth), but the dutch(or whatever else your rolling with) aswell.

However you choose to complete the L run is part of the adventure.
A: Yoooo blunt after school my dude?
B: Nah man I don't got bud or a dutch
A: No prob, i got my car, we'll make it an L run.
