A cripple rimfuck is when you are pleasuring the girl from behind and you take your penis and rub it around the rim of her rectum and if you do it just rite she will then motion as if she was a cripple in pleasure.
The ultimate act of supplication that a organisation will perform in order to win back your custom. After proffering everything possible the organisation in question is willing to pucker up and engage in the act of preforming anilingus.
It can also be used in the context of relationships that have broken down, where in one party is wiling to Rimback the other.
An example of how to use this phrase is as follows "A Multi Billion Pound British Broadcasting Company has reached new levels of low and in a desperate attempt to Rimback viewers to watch their programmes..." or "the average Beer company CEO is currently encouraged to Rimback any and all individuals willing to entertain them to buy their product". Another example is as follows: "We did break up, but in the end he Rimbacked me and now we are closer than ever" and "As your new Prime Minister I will stay true to our parties policies and make sure to Rimback your trust"
