A combination of the words "scum" and "summer" that perfectly describes summer living in Wellington, Florida. There's never anything to do during scummer and it's always 100 degrees outside. Characterized by extreme boredom that results in scummy group activities such as shaving eachother's heads, smoking mass amounts of weed and cigarettes, lurking in parking lots, and jumping off of roofs into pools.
Kid1: Man, scummer is so boring it actually motivates me not to brush my teeth in the morning.
Kid2: How does it do that?
Kid1: Well, I figure if I get a cavity it will be a good thing because at least I'll get to go to the dentist and that will give me something to do.
