Get Ready To Fill Your Own Slurpee Cup At 7-Eleven! (Photos)

If you have errant dreams of chugging a monster-sized ice-cold Slurpee out of a bucket bigger than your head, you're going to have a chance to realize your ambition on August 18 and 19.

On those two days, you'll simply need to show up between 11 a.m. and 7 p.m. with your teapot, vase, helmet or whatever you happen to have on hand, fill it up with whichever flavors of sugary slush you want, and pay $1.50 -- the price of an average medium Slurpee, according to PR Newswire.

"Each year, Bring Your Own Cup Day gives our customers the freedom to show their creativity in our stores and on social media," said Laura Gordon, 7-Eleven vice president of marketing and brand innovation.

"This year, we decided to give our customers the chance to double their creative expression by extending the fun to two days, August 18 and 19."

Of course, as with most food-related events, there are a few stipulations to limit your ability for enjoyment -- but they are pretty minimal.

The "cup" has to fit upright in a 10-inch display cutout, and it must be food-safe, sanitary and free of leaks.

PR Newswire notes specifically that "trash cans, kitchen sinks and inflatable swimming pools" are not eligible for this deal.

It looks like the rule enforcements are up to store managers' discretion though; BuzzFeed notes that past 711 BYOC customers have brought in zany vessels like sleds, prosthetic feet and fish tanks.

I'm not sure if this one will fly anymore:

But within the limits, you are welcome to get as creative as you like!

If you want, you can also pick up a limited edition super-reflective Chrome Dome Slurpee cup and lid (price unknown) through the end of August, or whenever supplies run out. And yes, you can come back with that cup for BYOC day.
