look up any word, like donkey punch:
 
1.
The average time it takes a weed lover to smoke their eighth. The length of an eighth week varies depending on several variables. These variables include, but are not limited to, size of bank account, employment status, and boredom level of the weed consumer.
Guy 1: How long is your eighth week since you got fired?
Guy 2: Dude, only like two days.
Guy 1: Whoa.

Guy 1: Man, I haven't seen that girl in an eighth week.
Guy 2: How long is that?
Guy 1: I don't know, like 4 days.

Scientist 1: We are running low on supplies, we must increase the size of our eighth week until this crisis is over.
Scientist 2: This is bullshit.
