When there isn’t a single dealer open in a 15 mile radius and you just smoked your last doob.
Or
A getaway line when you really don’t want to return someone’s advances.
In case of doobie drought:
Samantha: “I want to cry.”
Tenzin: “Why, whats wrong?”
Samantha: “Just finished my last nug, it’s going to be a long week. This town is drier than a lesbian in a male strip club.”
Hanna, to friends: “Tonight’s been so fun, it’s been great to see you guys”
Random Bobilly: “Hey beautiful, let me buy you a drink, I’ll make your night amazing.”
Hanna: “Aha, no..... The thought actually makes me drier than a lesbian in a male strip club. Bye.”
When a male inserts his penis into an oversized bucket vagina and realises that there is very little hope of getting any "purchase" hence unlikely to bust his nuts. Similar in meaning to throwing a hotdog down a hallway.
Brian: I couldn't believe my luck last night when I finally got to nail Felicity but my luck turned when I went to slip in my sausage and could not feel a thing!
Terry: I heard rumours that Felicity has a large bucket minge, Jeff said it was like a teatowel in a tumble drier
