The positive sensation experienced when you mix two things that are not normally mixed, just like the iced desert called a 'Splice' which consists of vanilla ice cream coated in pine-lime flavoured ice (Who woulda thunk it?!).
You could say that good-looking people of mixed racial ancestry are splicerific.
Jeremy: Hey Jackie, drinking hot tea with milk while eating a raspberry ice block is totally splicerific! I bet the others are regretting the fact that they didn't get stuck right in
Jackie: Yeah I reckon! I can completely relate to that!
Sven: I have no idea what you are talking about.
Jill: Me neither. I am experiencing extreme regret at not living outside of my comfort zone right now.
