When someone is tsunami shamed, their problems, big or small, are shot down immediately on the premise of ''At least you haven't suffered a tsunami''. It's hard to tell whether this is supposed to be comforting or or whether the person is playing the douche on purpose.
Two examples of tsunami shaming:
John: Hey Bob, what's up?
Bob: It's been a rough week. My dog got hit by a car, one of my parents lost their job, and I got a cold just in time for the finals.
John: Yeah, well, at least your house isn't three miles from where it used to be. Toughen up.
Linda: I heard you were moving to an apartment, Jane.
Jane: Yeah, my family's house is getting foreclosed on, we have to be out within a month. The only place I can afford is really small and seedy. I feel more sorry for my kids than myself.
Linda: Stop bitching, a least they'll have a roof over their heads, UNLIKE THE TSUNAMI VICTIMS!!!
