Best mascot in the country! Posted this to my story, then to Twitter and it has BLOWN UP. From local news to accounts like Sportscenter, Sports Illustrated, Barstool Sports, Fansided, etc. etc. …I haven’t been able to put my phone down since 10am due to people wanting to share it! So fun being back at the Marriott Center last night cheering on @byubasketball and @cosmo_cougar #BYU #Cosmo #viral
