Sealed With A...What?

My real-life true Valentine's Day story while at work and my conversation with one of the bakers as they set up a table of holiday cakes.

"So, what is this?"
"I dunno. They told me to decorate the heart cakes like those candy hearts. With words like Be Mine, UR Gr8, Luv You and SWAT."

"Yeah, SWAT. So what does SWAT mean?"

"Dunno. They just said SWAT."

"Maybe that was supposed to be SWAK."

"That doesn't make any sense."

"It does if you are saying Sealed With A Kiss."

"Oh, yeah. Well, they said SWAT."

"Sure they did. Okay, what's done is done. You can discount these tomorrow after Valentine's Day, right?"

They wonder why everything I say is prefaced with a heavy sigh.
