(zhy-fer) also spelled as zypher if you have a brain the size of a Asian penis. Zyhper is the nick

name of a mans legendary penis. And by legendary it means there are legends of it satisfying gods sister enough where he backed off, so legendary that your father would kiss it in hopes that he would get better, sooo legendary that your father even let your mother get cock slapped in hopes that she would start to fear his non legendary penis so that she can know what it could do if he ate all of his vegetables and shit that make penis’s awesome.

Dude watch out, i don’t call my penis zyhper just because i boinked your mother.
