Imagine Person 1 and Person 2 are on a date and are sitting on a bench while Person 3, someone who really ships them, is "hiding" in a bush behind them with mistletoe on a fishing pole hung above Person 1 and Person 2, trying to get them to kiss.

~^~

"Person 3..." Person 1 muttered while Person 2 was trying not to burst out into laughter, "It's July..."
Person 3 poked their head up from the bushes and put a finger to their mouth, saying, "Have you never heard of Christmas in July? Now, shush and kiss already!"
