According to the New York Post, these are allegedly the most offensive emojis broken down by generation: 

Gen Z – 🍑   

Gen X – 🍆 

Boomers – 🖕 

Millennials – 🍻 

As a millennial, I cannot explain why my generation hates the “cheers” emoji as much as they do… So make sure you send it to every millennial you know! 🍻
