danger sip

To take a swig of a beverage and follow it up by suddenly jerking your head backwards almost as if you were just shot in the face with a shotgun.

"Hey Robbo did you watch the footy last night?"
"Yeah mate it was heckers, how good was Dusty's post-match danger sip though during Cotchy's interview"
"Ahahaha fuck yeah, absolute mad cunt he is"
