Burns can either be a last name. Defined as: Strong, Hopeful, Mysterious, Happy, Passionate, Daring, Loyal, Polite, Outgoing, Athletic.

It can also mean that something is hot and it is scorching your fingers or leaving a red mark.

Without the S it can be a diss to some people. Or the same thing as what definition 2 was just non-plurial.
EG #1. Do you know Chloe Burns? Shes a really nice person, she makes a loyal friend. I can tell her anything!

EG #2. Ouch! The kettle's hot! It really burns my fingers!!!!

EG #3.
