Also the name of a cocktail

• Peach schnapps: colourless
• a dollop of Baileys: curdles into a white, fuzzy ball
• Grenadine: red colouring, spread around the outside of the shot glass

This used to be served by a friend of mine, Fiona, who used to offer to buy this for customers at the bar in Portugal if they'd drink it, or they'd pay and she'd drink it if they couldn't.

She never payed for a single shot.

Apparently, it'll make you gag if you try to sip it, so you've got to down it in one.
