I think I heard someone sometimes say this is some smartweed or smart grass, educational stuff, or something, grown at the local college (and it was good).
I like my stuff smart. Smart phone, Smart car, all that stuff is fine and dandy. I just don't like to get smarted.
(The source of “smart” is the prehistoric Germanic root word “smert,” which meant “to be painful; to hurt,” and which eventually produced our modern English “smart.” As a verb, “to smart” has always meant “to hurt,” usually literally, although later uses have invoked the word in a figurative sense.)
