When you are doing a girl doggy style (more points if its anal) and she is so tired that her arms have given up and she is laying facedown into the pillow. Just as you are about to ejaculate you grab both arms under the elbows, pull her back in an arcing fashion and in conjustion with your convulsion yell "KACK-KACK-KACK-KACK-KACK-KACK". Akin to Cuba Gooding Jr. in Pearl Harbor
When you don't have any money, you are low on cash, without funds, or just plain old "financially embarrased.
Hey girlfriend, me and my girls are going to check out that new movie, so how 'bout you? Sounds fun, but I can't this time cause I'm riding the greyhound.
First, you and three of your friends stop at a garage sale to avoid having to work out at track practice. Next, you find a broken cement goose sculpture being given away for free at that garage sale. Then, you and your friends carry the heavy goose sculpture over a full mile of hills back to your school track/football field, even though it would have been much easier to drive the sculpture back in your car.
