Merome or ASFCanadian is pretty much the most popular fanship among Team Crafted and other Minecraft Youtubers (other examples being Sparkant, Skylox (probably the second most popular), and Trulox, among others). Almost every fan of TeamCrafted knows of Merome and the guys refrence it in many videos, including their Pixelmon series.
Ian said in a tweet on Twitter "#Merome for DAYYYSSSSSS" then mentioned Mitch and Jerome, followed by a fake picture of them kissing.
Despite not being in a relationship, as Jerome is publicly in another one, both Jerome and Mitch make fun with and/or accept the fans shipping them, especially Mitch. Merome is almost always typed as #Merome due to its popularity on Twitter and Instagram.
