An adjective describing an indefinite, but painfully large, period of time or amount of something.
This phrase is often doubled: "for days and days" to stress an even larger period of time or amount of something.
(Usage Note: In Northern California, this is often paired with the word "Hella" to add even further emplasis)
1. "This pop tart has been toasting for days..."
2. "That chick's legs went on for days!"
3. "This party's going to be hella tits for days and days!"
