Get a thesaurus and split hairs all you want with different terminology. Sometimes, what you do is defined by what you don't do and in this case, you don't want to just yank on that trigger.
Even in the definition of "squeezing" the trigger, some people will squeeze their whole hand and throw their aim off. Instead, they need to just squeeze the trigger finger. Or, make sure that the finger is just pressing on the trigger to move it straight back rather from one side to the other.
Then again, application has a lot to do with how you train and how you shoot. If you're shooting bench rest, you'll probably use that trigger a lot differently than if you're shooting in combat or competition speed games.
