Clever wordplay? When I saw "Uber" I thought the word "gig" referred to a small, horse-drawn carriage. (After looking it up, I see that gig can also be "a light, fast, narrow boat adapted for rowing or sailing".) Then I thought maybe she meant it's harmful, so maybe she meant the pronged-thing-on-a-handle, also known as a frog-sticker. Finally reading the comments, I realized "gig" meant an un-contracted, one-off performance.
