The first meaning of these words was based on the word Jizz but made for open use so the true meaning was to stay hidden from public use such as... Parents, friends or just about anyone that would say Lolz or Gay at you for the use of what the word was on.
But later became a word for more then what it was first was used for. Now it is also used to describe moments of intense joy, excitement or pleasure for the eyes ect. With the same strong meaning.
