When you and a number of other people are in a casual conversation and you secretly begin to masturbate. Just before reaching the ejaculation, WHIP OUTCHA COCK and EXPLODE all over one of the female's faces.
'Yo Jefferson Black Man, I was mingling with some friends on Saturday and Taneisha gave me a dirty look. To get back at her I gave her a surprise facial!'
'You mean like cum?'
'Yea man, she was fuckin glazed.'
