What is a smart and creative way to remember the definition of simultaneously?

Simultaneously means at the same time. I have a project for English class to find a smart and creative way to remember the definition of simultaneously. It can be of a drawing, a symbol, of rhyming words, or of any thing else you can think. It has to specifically do with simultaneously. I am not a very creative person and your help will be very helpful. Thank you very much.|||you could draw two simple objects (circles?) with arrows extending out of each, and make it perfectly symmetrical
