Haha. 광탈각 is compound word of 광탈 and 각. Let’s get start with 광탈 first.
광탈 is also compound word of 광 and 탈. 광탈 means be dropped of something out of the gate. (광means light, it is considered as modifier, means in an instant, because nothing can exceed light speed. 탈 is abbreviation of 탈락 means be dropped of or be rejected.)
각is suffix, and i think it is vogue word, usually used by teenagers or twenties. Means some kind of feeling that lead you to beg the question. So if you add 각 like this you think they maybe be rejected in high probability, but it is not 100% but just your thinking.
I think this kind of word belongs to slang, it soinds funny but it could be sounds weird to some people.
