Suckerpunch comes from the word sucker, which means someone who is naive, gullible, easily tricked. A suckerpunch is delivered to the dupe who fell for a con or a trick and got punched. Low-brow British humor is loaded with suckerpunches. The cabbie in Bill Murray's Scrooged! yells "so long, suckah" when as the Ghost of Christmas Past he dumps the Murray character off. Much more than just a punch you weren't expecting. Also used by naracissists and sociopaths in relationships where they are using an innocent person for their own purposes and then dump them without an apology or explanation.
The suckerpunch is typically delivered by fist to the solar plexus, knocking the wind out of someone. But suckerpunches can take many forms. In a relationship suckerpunch the "sucker" receives a severe blow to his/her self-esteem, trust levels and maybe even sanity. The suckerpunch consists of sudden, inexplicable emotional or verbal abuse, delivered after weeks or months cultivating the trust of the other person. Example: "Maybe you like me but I don't like you." POW!
The act of putting one's fist in the vagina of a woman on her period, thus making your hand bloody. After this you yell "HEY!!" and when she turns to look at you you punch her so hard she gets knocked out then walk out of the room.
First you take any random girl that has her period, this is important. Now you fuck her in the pussy, and proceed to fisting her really hard. Dont wipe your arm. Then you turn her over and have hard anal-sex. Then just as you are about to cum, stop and spit on her back. She will turn around and you cum in her face, knock her out cold with your red and bloody fist and then you draw a moustache on her.
Man, me and my dad was dealing out Dirty Sanchez with a Raspberry flavoured Suckerpunch all last night
