Someone busted out the dictionary, I think I'll show it to you again.

a. an instance or period of being under the influence of a hallucinogenic drug, esp. LSD.
b. the euphoria, illusions, etc., experienced during such a period.
c. any stimulating or exciting experience: The class reunion was a real trip. --- or That high was a real trip ---
d. any intense interest or preoccupation: She's been on a nostalgia trip all week.
e. a period of time, experience, or lifestyle: Those early years in college were a bad trip.
And obviously you do care, because in the beginning of the thread, two times you pointed out people's "MISUSE" of the word trip. You do care because you're still posting.

Words take on different meanings in different regions, and words can evolve due to slang. If I say something is cool, it doesn't necessarily mean that it was lacking heat temperature-wise. Here's the thing that'll blow your mind --- "Cool" only used to have one meaning, now it has more than one! OMG!

"Trip" at one point may have very well only been used to describe what can happen when taking psychadelics or hallucinagens, but it seems to me that quite a few people are using it simply to describe a strong (or insanely strong) high.

And if you want to mke your own language, go ahead, no one's stopping you from doing it, but no one will understand you, and most will probably think you're crazy.
