A trigger is actually something pretty difinitive.

Thunderstorms trigger me.
Someone calling me a bi*** or stupid or no good triggers me
Someone looking at me with a rage filled glare triggers me
Someone demeaning me or another in any way triggers me
Someone diminishing the effects of abuse or victim blaming triggers me

Yes these are a lot of triggers- but I have them because I went through many things and those are things that actually put my mind so far back into the event it feels as if I am experiencing it again. I have learned to control some of my reactions to some of them to an extent - but the fact they are there does not change.
