Have you gotten a Fetty Wap receipt yet?

The 2015 summer anthem “Trap Queen” by Fetty Wap begins with the rapper shouting out the number “1738,” a reference to a brand of cognac and to his crew back in New Jersey.

The shoutout is one of the more memorable lyrics in “Trap Queen”: When you hear the 1738, you know it’s Fetty Wap time. There are 1738 T-shirts and bumper stickers and novelty license plates, and the Kansas City Royals recently played a prank on the media by jamming the numbers “17” and “38” into as many interview answers as they possibly could.

1738 has become so ingrained in our culture, in fact, that it is now a much coveted final amount to receive on your receipt. A grand total of exactly $17.38 at a restaurant, or a grocery store, or a bar is a treasure, a mini-lottery that you win at the cash register; the Fetty Wap receipt can bring color to an otherwise drab or mundane checkout experience. Judging from tweets and Instagrams, there is nothing quite like receiving your final total and seeing that it all came out to exactly 17 dollars and 38 cents.

Many have taken to social media to enthusiastically share their receipts.

It’s happened at Domino’s:

At the local Wawa:

Usually when you get a receipt for $17 or so, you crumple it up and throw in the trash. When you get the Fetty Wap receipt, however, you want to treasure it forever:

Even if you’re the cashier and not the actual owner of said receipt:

Buying exactly $17.38 worth of items is difficult, of course. So another way to achieve the Fetty Wap receipt is to leave a tip of $17.38, as these restaurant patrons in Oklahoma City apparently did.

Or if you’re tight on cash, you can just tip an amount that brings your total up to $17.38:

You can also include an illustration for good measure:

Really, though, it is difficult to match the sheer exhiliaration, the rush of adrenaline you get when the cashier hands you your receipt and you see that you hit $17.38 right on the nose:

…followed closely by the disappointment of spending one penny too much.

There are certainly calculations you could perform to determine exactly how to combine certain foodstuffs with certain prices to get to $17.38 on your receipt. This is cheating. Like “Trap Queen,” and the introduction of Fetty Wap’s “1738,” the phenomenon is best enjoyed when it arrives by surprise.
