Merriam-Webster: any of an order (Thysanoptera) of small to minute sucking insects, many of which feed often destructively on plant juices. OED: noun. slang for threepence. Usage: "A little boy who wanted to buy a thrip's worth of candy." Also verb. To make a noise with thumb and fingers; to snap. I like Merriam-Webster better.
