Has a guy ever "mansplained" something to you?

Rebecca • "You only live once, but if you do it right, once is enough." YASSSSSSssss.
It's when guys assume you don't know something because you're a woman and then proceed to explain it to you like you're a child. 
Anyway, my friend has a coworker that questions everything she does and then mansplains why, even though she's obviously already thought through all of his concerns. Such a jerk. 
Have you experienced something like that?
