adjective-a higher level of fantastic that is almost surreal. or the fusing of an activity that is the "bomb" and a situation or mood that is already fantastic. or feeling such a good feeling during any situation that a sensation is obtained of which you believe your going to explode from sheer joy.
1) man that party last night was bombtastic
