Why clink glasses in a toast?

You tell me! It's pretty naff in most settings nowadays. 8 people around a table ostentatiously clinking glasses before tucking into their oaked chardonnay. "Ee nan, that's reet grand that wine" Clinking the glasses ,one should only touch the ones to the left and right.To touch others is redundant and shows low class.This glass touching it done to show group unity,solidarity if you wish. --------------------- I heard this on a Movie - Tortilla Soup - It's somewhat paraphrased: You clink classes in order to experience the 5 senses: Clink glasses to 'hear' the toast - Touch the glass - See the color of the wine - smell the fragrance - taste the flavor. Seems reasonable to me ! ---------------------
