To "get sendy" means to go all in or give something your full effort and commitment, often with abandon and daring. The phrase originated from the sports term "send it," which signifies 100% commitment to an action, and it has become popular among teens and in sports or party contexts as an expression of enthusiasm and boldness. It can also involve playful behaviors like pretending to "shotgun" food or drinks in a fun, exaggerated way.
In summary, "getting sendy" is about doing something with full commitment, excitement, and sometimes a bit of reckless abandon.
