I personally don’t refer to Big Wally by the word “pecker”. But “peckerhead” and “peckerwood” are often names I bestow on my fellow motorists.
Non sequitur time. I’ve always wanted to sleep with a guy who calls his dick Dagon. 
That is all.
y’all have me wondering about names now.
as dick is the more in vogue name now-a-days, i notice there are less guys nicknamed dick. they tend to be older guys (there are a few exceptions ie a certain car racer, and baseball player) like the vp. most young guys are rick(y)s, rich(ie)s, or full name richards (pause for the jane seymour scream).
i don’t met many baby boomer or older peters, but there seem to be a whole slew of them in the 20-30 age group.
any thoughts?
Yeah I only hear pecker as part of “peckerwood.”
Mine is my “unit” or “Little <myName>” Not that it’s little or anything. Just littler than me as a whole. Had to clarify that, whew.
You also hear it in the phrase “Hotter than a two-peckered billygoat.”
Around here it’s “Hotter than a three-petered tomcat.”
Around here it’s “Wow, it sure is hot out.”
As Sanity Challenged said, pecker is only used for comedic effect. But I do use it in that context to good effect on occasion. It’s connotations of small size, insignificance, and sexual annoyingness come in handy.
I never really hear peter used. It’s just as archaic, but somehow it’s just not funny.
One guy. Used every name there was to refer to his male organ. It was worth talking about …
