Sporadic 

Inconsistent; difficult to predict.

Last year's winter was characterized by sporadic showers followed by long cold spells.

Sporadic 

someone who stands in the middle of nowhere drooling.
they often where their pants as high as they go. they have little friends (only pity friends)
they have a lot of stupid problems, like having egg heads.
they don't know the difference between emo and prep and they cry a lot.

Sporadic: hello!
me: oh...hello (hesitation)
me: you have an egg head
Sporadic: nuh-uh! (tears)
me: your so mean
Sporadic: the world treats me like shit, so that's how I treat it...
Sporadic: you cussed...(runs away crying)

now those are Sporadic

Sporadic E 

Irregular scattered patches of relatively dense ionization that develop seasonally within the E region and that reflec­t and scatter frequencies up to 150 MHz. Note 1: The sporadic E is a regular day­time occurrence over the equatorial regions and is common in the temper­ate latitudes in late spring, early summer and, to a lesser degree, in early winter. Note 2: At high, i.e., polar, latitudes, sporadic E can accompany auroras and associated disturbed magnetic conditions. Note 3: The sporadic E can sometimes support reflec­tions for distances up to 1000 miles or more at frequencies up to 150 MHz

I got some nice 6-meter DX contacts with yesterday's sporadic E.

Sporadic Minstrels 

Ultimate's not good enough. We're talking, ultra-splendiferic conceptualization of Charles Sheen taking large stamps on small biscuits.

Sam: Hey Sam, Sporadic Minstrels are the Don Mecca.
Sam: You don't say?
Sam: I do say!
Sam: How do you say, Samuel?
Samuel: I don't say, how do you say, Samantha?
Samantha: I say.
Sam: Charles Sheen!?
