From Ancient Greek Τριπολιτάνια (Tripolitánia), from Τριπολίτης (Tripolítēs, “Tripolitan”) + -ία (-ía, “forming abstract nouns”), from Τρίπολις (Trípolis, “Tripoli”) + -της (-tēs, “forming abstract nouns”), reanalyzed as Τρίπολ-ῑ́της (Trípol-ī́tēs) (compare πολίτης (polítēs) and Latin -ī̆tānus), from τρι- (tri-, “three”) + πόλις (pólis, “city”), referring to the three cities Oea, Sabratha and Leptis Magna.

From treat + -er.

From un- + alive. Internet usage originates from circumventing social media algorithms that were believed to penalise the use of the words related to death, especially “die”, “kill”, and “suicide”. According to linguist Adam Aleksic, the word in the verb sense of “die, kill” first appeared in a 2013 episode of Ultimate Spider-Man, exploding in usage after a few viral videos in early 2021 popularized it. Since early 2022, unalive has become very widespread even outside Internet usage contexts, especially among adolescents. Aleksic argues that the word unalive has gained so much popularity because of a time-invariant tendency to refer to death by euphemism; compare the word die’s displacement of swelt, or the use of pass away.
