The act of sniffing with the loudness and intensity of a wild dog - usually while sniffing a partner's neck or arm or
leg in order to ascertain that they are the
real thing and not just a clone sent to
trick you (which is totally possible in this day and age).
Please
stop you're messing up my hair, you
don't have to schnuffle me - I
promise I'm your wife and not just a replicant.
