Memes that are usually never funny even the first time people make them and used solely for the purpose of being made over and over 'till people are sick of hearing them, like putting cold food on a microwave, hence the "microwave" part. First told in a lyric by Kendrick Lamar's song N95 where he said the word to express the staleness and cheapness of reused social media memes
"Take off them fabricated streams and them microwave memes, it's a real world outside (Take that shit off)"
