To have someone (a male), orgasm (aka: cum) on your face, in a similar manner to a facial.
Gluing is not necessarily limited
to the face, this is
merely the most common context in which the expression has been found.
Much to
Mary's chagrin, her boyfriend pulled out at the very end of a blowjob (as if suggesting her was going to
tea bag her), and glued her face instead.
