Frankenstein coffee 

When you have a normal cup of coffee with creamer and you add more coffee to it and have to match your previous creamer with the proper amount of additional creamer, so you have to experiment to make it just right and the experiment can go horribly wrong and ruin the entire cup. Like Frankenstein.

"Dude I hate having to make Frankenstein coffee."
