Definition: The slang term for "retest" is "sweat test." Imagine someone taking a body wash and then putting it on again because they're feeling the need to check their skin for sweat; just like they do after a bath.

Here's an example: A group of friends went to a fancy restaurant for dinner. They all got there at different times, but their waiter noticed that their waiter was still waiting behind them when it was supposed to be them in line. "Hey, you're not here," the waiter said to the group. The friend who ordered pizza got there last and then started sweating profusely from excitement; he couldn't help but check his shirt. The other friends were stunned; they never noticed until their waiter came over. So, what do you think? Is it a test of patience or just plain lazy? Let me know in the comments if you have any more fun slang terms to add!
