Tina: I just bought some ethyl hexanoate from my local chemical store.
Jonathan: What are you going to use that for? Why do you need this random ester?
Tina: It smells like apple peels, I am going to use this in my perfume.
Jonathan: Don't the two components of the ester, hexanoic acid and ethanol both smell pungent? How can they come together to smell, well fragrant?
Tina: Under an acid catalyst, CH₃(CH₂)₄COOH+CH₃CH₂OH→CH₃(CH₂)₄COOCH₂CH₃+H₂O.
Jonathan: Uhhh what?
Tina: C h e m i s t r y.

To say when everyone has used up the words more, most, -est, and -er. You add -ester to any word (mostester, gayester, etc.). Very helpful because the person your arguing with will have no idea how to respond to that.
Person 1: Your gay!
Person 2: Your gayer!
Person 1: Your gayest!
Person 2: Your gay-ester!
^clearly person 2 wins^
Person 2: Your gayer!
