when receiving oral sex from a female, one ejaculates onto her face and she proceeds to light a cigarette without cleaning off the semen. while not necessary, it is encouraged to shout "happy birthday" whilst ejaculating. without cigarette, referred to simply as "icing" the cake.
My girlfriend ran out of menthols, so had to use one my smokes when I gave her her face cake last night.
