I think some people are taking TikTok wayyyy too seriously. Marissa isn't doing anything that my little cousin isn't doing with her friends in college right now on TikTok. Ridiculous dances, quoting songs/movies, recording friends doing dumb stuff, etc.
We're not the demographic these videos are made for so yea they're pretty cringy to us. And just like I look back at my old vines and ask myself 'why I ever thought that was funny' I'm sure this generation will do the same with their videos someday.
Saying she is an embarrassment to the team because of TikTok is so overdramatic. The team would much rather her do silly little skits then party at 21+ clubs.
