A gentelmenly, over enthusiastic vocalized expression of supreme delight, exhilaration and triumph when greeting and welcoming a close friend or loved one. Adapted from post cold war pop culture references to blissful, timeless rhythmic engagement in Easter European Dance Halls, the term "Days" personifies the intensity and joy of the moment in the presence of partners (i.e.friends or loved ones). Sometimes spoken with an indistinguishable European accent. In cases of suprise greetings, 'Days' is used in conjunction with the word 'Hey', as in "Hey Days!"
{Friend enters room} "Days!"
{Friend enters room, surprising and overwhelming you with joy} "Hey Days!!!"
