1. Simply good, simply delectable, simply delicious. Like salt, use it sparingly to add a twinge of spice and sophistication to any conversation.
2. An uncommon moniker for males. Stems from Saint Simplicious (1351-1392), the patron saint of silly names.
"Oh Sebastian, the Beef Wellington was simplicious!"
After the ballgame:
"That umpire's calls were all shit. Totally NOT simplicious, dude."
"Sweet Jesu, Gwendolyn, where ever did you learn to do the cocoa steamer? Simplicious!"
"Yo Simplicious, get your ass over to Tommy's house before I shank you."
