Having your (gay) partner secrete out their
feces (preferebly in a stick shape), then
covering the feces with wax and inserting a
firecracker in said wax.
Next you must let the wax harden before inserting it into your (gay) partner's anus and lighting the firecracker.
After it explodes you proceed to take it out of your (gay) partner's anus, then proceed to suck and lick the feces (inserted inside) like a popsickle.
