Are events raised, triggered, or fired? (stackoverflow.com)

Exceptions are raised. Events are triggered. Callbacks are fired.

Speaking colloquially, I'll often use "pop" as in "Do we have a log of when that event popped?"

In plain english, events "happen". E.g. "If this event happens, then...."

If you want to emphasize that the event has just been created, in plain english you would say the even has been "caused". E.g. "The user clicks the mouse button, which causes a GUI event...."
