While smoking a joint or bowl of marijuana, if someone says the phrase "Sean Connery says schmoke it" (in his accent of course) then the amount that is left must be finished by those who participated when the joint or bowl was lit. This is referred to as "calling Sean Connery." This term is classically used only once per day among a group.
Travvy: Maaaaan...... I'm too baked, i'm done.
Timmy: "Sean Connery says schmoke it"
Travvy: Well, you've got to obey the Sean, hand it back.
