Multi-Colored Duck-Tape

Okay, so I've been noticing a trend a lot. Now, people are wearing duck-tape on their clothes. WHAAAAAAA? Yes, people are using duck-tape for EVERYTHING! Clothes, projects, fixing things, and so much more! Because of this, people are making different colors of duck-tape. Why is duck-tape so popular when worn on clothes? I just don't understand it. Some people wear pink duck-tape for breast cancer help, or whatever. Now, you see it worn everywhere! I just don't understand it!
