Full house, pooperscoopers high

I biked to a local park with Sydney, and on the basketball court, amidst a whole lot o fother chalk drawings, was the word “POOPERSCOOPER” in huge, careful chalk letters, which struck me as funny.

Sydney stared at it for a second and said, “I get it.” I said, what?

She pointed at 3 similar words, each one at the corner of what would be a 40 or 50 foot square, with the same chalk and handwriting. The other ones said “KING,” “QUEEN,” and “JACK.” She said they’re kinds of cards.

I guess an ace in some circles is referred to as the pooperscooper. Like “Full house, pooperscoopers high.” Which also struck me as funny.
