Not slang, but yet another example of folk etymology...

"Strawberry" has some connection with "straw", right? Like the plants are mulched with straw or something. After all, one of my garden books makes that connection. Wrong. "Straw" is a variant of "strew". Strawberries grow "strewn along the ground" instead of on canes as raspberries and blackberries do.

Just more useless information.
