Get the Gas Happy mug.
1. A period during the day (usually in the early morning and late afternoon/evening hours) that can typically last for about a half hour or longer, when everyone seems to need gas in their vehicle at the same time and so every gas station you go to is overrun with lines of people waiting to pull up to the pump.

This can become quite irritating and inconvenient when you need to go somewhere quickly, but you need gas to get there.

Aw man, its freakin' gas happy hour again!!!
