Another way of saying ball sack. The paired words, dating back to 2009, originate in the north eastern area of Portland, OR. When the words are used separately, "syke," has a completely different meaning, which is "to suck" or "one who sucks." "Byke," on the other hand, still means "balls," but it can also relate to "biceps" depending on the words it is paired with, or "bike," for obvious reasons.
What's wrong dude?
My byke syke's really itches.
What'd she do after you said that?
She punched me in the byke syke.
