(Verb) To insert both the penis and entire sack of testicles into a vagina and/or anus. The act of "armstronging" usually requires using both hands to help stretch the vagina and/or anus hole to allow for total insertion.
"Dude, that chick's pussy is so loose, I practically armstronged her without using my hands."

an "armstrong" is a person or people who take their cycling too seriously. They travel all over the city in their tight, spandex bike suits, goofy helmets, backpack drinks, and their livestrong bracelets. They treat everyday in the city streets like it's the "Tour De France." They are known to ride fixed gear bikes. They act like they are better than everyone because they are living strong, when in reality they were dead a long time ago.
I was walking down the street with my three year old child when a bunch of rabid Armstrongs nearly ran us over
