eli5 why is a little inflation good for the economy ?

"The economy" is just a term for "money moving around". 

If you think your money will be worth *more* next year or the year after, then you have incentive to save it until then. More people saving money instead of spending means less money moving around, which means a weaker economy. 

If you know your money will be worth the same or less next year, then you have incentive to spend your spendable money now. More people spending money means more money moving around, which means a stronger economy.
