The #WasteHisTime2016 hashtag first erupted on Twitter in early January 2016, becoming a massive viral phenomenon where women shared humorous and often petty ways to frustrate men they were dating. The trend typically involved scenarios like leading someone on, taking hours to reply to a text, or making plans with no intention of showing up. While it sparked some controversy regarding dating etiquette, the meme was largely embraced as a satirical response to the 'fuckboy' culture of the era. Today, it remains a nostalgic touchstone of mid-2010s internet culture, used to describe any situation where someone is being intentionally difficult or playfully devious in a romantic context.
