What is Heat Shield?
1.
A sexual act which involves one wrapping their face in saran wrap and then having his/her sexual partner deficate on to the surface of the saran wrap. The heat from the feces will warm the face. WARNING: Death from suffocation may result...but if you're sick enough to be doing this, the world is probably better off without you.
"I enjoy the warming sensation of the heat shield all over my face."
