A sloggy doggie can be defined as a hot dog where the wiener is cooked by the heat from inside of a freshly worn rental skate from roller skating rink.
Now that I'm skating I am so hungry but I don't have much money because I spent all my cash on the tonight's skating session. I only have enough cash for a sloggy doggie. PLUS I have been skating for a while and my puppies are hot. I know that my skates will cook those sloggy doggies so quickly!!!
That cheap crap you bought when you were a kid from a 25 cent machine and after 17 minutes it breaks. Expert children say that 20% of the time during the years of 1990 and 1998 the most common disappointing 25 cent toy machine item was in fact the plastic mini-slinky. When you get older you buy cheap furniture, cheap equipment, etc. and it breaks or is flimsy can also be considered a "cheapy slinky."
I just bought this necklace yesterday and it broke already. Now I know why it cost $2.99. What a cheapy slinky!
