When a girl is giving you fellatio, and you put her in a leg lock so she begins to choke on your penis. While stuck, you take two fingers and smear poop on her upper lip, giving her a Hitler moustache. When you release her she will be wheezing on the ground with said moustache, and will have received the Asthmatic-Hitler.

David: For what?
Steve: I gave that girl the asthmatic-hitler and she died
David: Sucks man..
