When one is experiencing extremely high levels of various emotions that may agitate another person in their company and really needs to just chill out or relax, the annoyed party in their presence can tell them to take a chillaxative, therefore rendering it appropriate for that person to fully let go and purge their stresses until they reach a serene state of calmness.
