a dude who is constantly flexing and or checking himself out, a ziemke will usually hit on younger girls, preferably in highschool a ziemke has a small penis and thining hair, a ziemke will also fake a deep voice to make himself more appealing to the ladies.
That new gym teacher is totally a ziemke, look at him hitting on those freshmen.
