Sober Saturday 

A challenge for most high schoolers and college students to refrain from all substance usage for one Saturday in a month. If they loose they’re a bitch.

A day where gabby decarlo’s only choice of substance is Jesus.
Hey gabby! You know what day it is?
No
Sober Saturday! So sober up or you’re gay!

Sometimes Sober Saturday 

A Sometimes Sober Saturday is a Saturday that qualifies as being sober. This can be for any reason. It is really more of an event, than an adjective.

Joe: "Man, last night was boring, I had a sometimes sober Saturday. :("

Tim: "I've got a lot of homework, I think I'm going to participate in a sometimes sober Saturday."
