Mine was OS X dictionary IIRC, but here's dictionary.com:

adjective, Also, epical 1. noting or pertaining to a long poetic composition, usually centered upon a hero, in which a series of great achievements or events is narrated in elevated style: Homer'sIliad is an epic poem. 2. resembling or suggesting such poetry: an epic novel on the founding of the country. 3. heroic; majestic; impressively great: the epic events of the war. 4. of unusually great size or extent: a crime wave of epic proportions. 5. Slang. spectacular; very impressive; awesome: Their burgers and fries are epic!

So if (4) is what you mean, it's not exactly the first definition for the adjective either.
