This thread is for naming things that you're surprised ever became popular with the public. Things or attitudes etc. that you're puzzled at why anyone would spend hard earned money on them, or adopt them as a personal style, or spend lot of time keeping up with them etc.
For me, here are a few:
( A. ) Professional wrestling
( B. ) Movies showing implausible situations where not much happens except a lot of gullible or stupid people getting slashed and smashed up, and/or chased around.
( C. ) High priced costume jewelry
( D. ) "Reality TV" shows that seem scripted.
