When a girl is giving you head and when you are about to cum, instead of warning her beforehand, you grab her head and jam it down on your cock and let loose, causing sperm to gush out her nose and creating the 'ice dragon' effect.
Essentially you pump around three litres of ice dragon cider into your nasty girlfriend's arse which you then plug using your member, hanging onto her hair (preferablly pig tails) you shake that bitch up like a fizzy drink then ride her half way down the stairs. At this point pull out and let the ice dragon propell you both towards the bottom of the staircase. Pull hard on her hair and try to face plant that tramp against the door. If successful, teeth marks will be evident along with her bloodstained face.
"I rocket rode that fat potato faced caroline so hard her teeth got stuck in the door"
"I'm a motherfuckingice dragon rocket rider!"
When a man cums in a womans mouth while recieving head and the cum is still inside of her mouth the man goes behind her pulls her hair back and whispers he has an std causing the cum to squirt out of the womans nose.
