GAME: You know your penis is big when...

[Gundari]

You know your penis is big when you black out every time you get an erection.

when you break your leg and you can walk just fine

when you get an erection in bed and hear a plane crash right above you.

This reminds me of the song by Mickey Avolon - My Dick.

but when even the loosest girls are still complaining your hurting them.
when you get a blowjob, and ask them to stop dragging their teeth, and they say their mouth is open as wide as it will go.
when you can see her stomach poke up when you are stickin it in.
when you and a girl first hook up, and right before you stick it in, she grabs it and her eyes get huge, and tells you to be gental.
when you dont have to tell some story about how big it is.
when a girl asks, and all you say is you'll find out.
when you were in highschool wrestling, you had girls come up and give you their phonenumbers because of what they seen on the mat.

when you don't shake after pissing --- you just kick it in the head with your foot.

[Infamous]

when you can tie it to the entrance of a maze so you dont get lost

[Infamous]

when you feel yourself cumming and then three weeks later it actually comes out

[The Baked Head]

.......when you can get a girl "preggers" a few miles away
.......when you can tie it to a boat and watter ski without holding on to anything
.......when you get banned from all the public washrooms in your city
.......when you use it to hide your favorite stash inside
.......when you can hit a baseball without a bat
.......when the total length is: "unknown"

whoa alright no more thinking about dick for me, time to go back to vagina

it learns how to harness the Force.
it looks at you and asks where it came from. And you answer that it was designed by Masons and erected by 15 stonemasons, two stonecutters, three carpenters, one helper, one rigger, 33 laborers, and two watchmen.

When your talking to a girl and she stares at it. Can't believe women are such hypocrites sometimes
