The modern version of the word "true" or "trillz." Qwetru has the word TRU at the end so it sounds somewhat like true. Qwetru is a new popular slang word that started in New York used by middle and high school students. Qwetru was made up by typing random letters before saying true, spelled without an E at the end, and it stuck. Now everyone uses this word.
