My uncle Jack's off

A very funny "childrens" book written by Bo nehr, that includes multiple references to "Veiny Necked Birds", "Big Hairy Sacks", and "White Sticky Trails". The title of the book can be misleading to some, so to clarify, the apostrophe between the K and the S is replacing the letter I, so the title of the book is actually "My Uncle Jack IS Off", for all you dirty minded schlongs out there

"I just read My Uncle Jack's Off, and laughed my shitties out!"

help your uncle jack off a horse

A capitalization error, the difference between "Help your Uncle Jack off a horse" and "help your uncle jack off a horse"

Cowboy 1: Hey, partner! Go help your uncle jack off a horse!
Cowboy 2: How many times do I have to tell you, it's "help your Uncle Jack off a horse!
Cowboy 1: Oh, sorry for making that homosexual grammar error!

uncle jack hasn't come by today

This is when a guy/girl hasn't had the time to do his/her daily jack-off and is pent up and taking it out on others. If you are not a daily masturbater then this could also be used as "uncle jack hasn't come by this week/month"

"I'm sorry for being a jerk, uncle jack hasn't come by today and it has be all riled up"
