Knobbed him with a Python 

The most satisfying kill in Call of Duty: Black Ops.

Can have the pronoun changed as required, such as Knobbed him/her/them with a Python.

Often followed by a battle cry of "Python!"

I ran round the corner and someone fired an RPG past my head, so I knobbed him with a python, happy days!
