Halfcore 

Akin to halfcaf coffee, and just as you would likely expect, halfcore is half of what hardcore is. Only a fraction of the dedication.

I was playing a game the other night, but I was busy reading online comics at the time, so I was only grinding halfcore.

Halicore 

Combination of Hardcore and Halitosis (bad breath)

Halitosis is used to describe cases of bad breath so extreme that only human excrement or rotting fish can match it for pong.

Man your breath is halicoreee get some damned mints
