A drink typically brought out at uk university rugby socials, but can be found at many sports socials.

Made of Guinness, baileys, and lime.

The lime curdles the baileys in the Guinness, making a foul concoction commonly used as a punishment at these socials. The best way to drink it is to chop it as quickly as possible.

Most often found at Durham university.
