A 'trigger' is a term which refers to sights, sounds, smells etc. that cause sufferers of PTSD to relive memories of their trauma and give them severe physical symptoms like muscle tension, increased heart rate and so on.
Tumblr has overused the word so much that they now refer to things you just find generally offensive as 'triggering'.
