The 'Masvingo' meme is when people attribute funny images or videos to the province of Masvingo. This started in July 2017 and spread mostly via WhatsApp groups and facebook.
Noone can say for sure how or who started this meme. Some people suggest that it may be a political campaign from within the Zanu PF's 'G40' faction. The allegation is that they want to demean their oppenents through this meme. Others suggest it may be 'tribalism', a remnant from Zimbabwe's colonial era.
