Bonus combination example: "I met Jenna at the bar when we both ordered a 'Mexican brain surgeon." We toasted together and joked around a bit, then ordered another round. Fortunately, the liquid 'Mexican brain surgeon' did its job and I was able to do my own 'Mexican brain surgeon' on Jenna later that night. Giggitty.
