Hashtag Exaggerated

We were on the way to the shopping centre when, about 2 minutes into the trip, we realised that we forgot to buckle up Ethan's seatbelt.
Ethan: I'm not buckled!

Me: Oh! I'm sorry. (pulled to the side and helped him buckle up)

Ethan: Oh my God, I can't believe I survived that. I think I just cheated death! Hashtag Ethan is lucky!

I'm not sure which is funnier - the exaggerated reaction or the hashtag added to it.
