SMASH THAT MOTHAFUCKIN’ LIKE BUTTON 

A command used by several YouTubers intended to dramatize their words telling you (the young audience) to click the like button for their video, regardless of your truthful opinion of the given content. There are many ways to achieve this goal as a YouTuber, like by adding dramatic, inciteful words such as “SMACK,” “HIT,” “ABUSE,” “DESTROY,” “WACK,” etc.

Other ways of fulfilling this include giving your audience limited time to click the like button with a countdown, using it as a necessity for them to win your totally authentic giveaways, telling them that something fortunate will occur in their lives if they click the button, or telling them that something unfortunate will occur if they do not.

YouTuber: “SMASH THAT MOTHAFUCKIN’ LIKE BUTTON, YOU GUYS, AND SANTA WILL APPEAR AT YOUR DOORSTEP WITHIN MINUTES. THIS ACTUALLY WORKS! I AM NOT KIDDING!”

Audience: “Yeah, yeah. Fine, weird stranger commanding me through a screen.”
