A penis on a transsexual woman, this sort of cock is ultra feminine and is completely female in the context of sexuality.
A penis in this context is part of the male to female transsexual's feminine identity, and therefore is female (not in regards to chromosomal sex ie. xx or xy, but in regards to gender identity).
Some transsexual women lose the ability to ejaculate and become erect due to hormone therapy, however the functionality of the penis has nothing to do with whether or not it is a "shecock."
A woman or man is 'shcocked' when they see a man's penis for the first or second time and are shocked or surprised or impressed at the length, girth or greatness of the member.
One may be 'shcocked' to the upside or to the downside- at a penises greatness or lameness, however, this word is more typically used in the context of an impressive, rather than disappointing member.
OMG- I saw his dick last night for the first time and was completely SHCOCKED! It was bigger and better than I could have ever possibly imagined!
When you are running a tad bit late so you must move real quickly or "shacockle" to get thereon time.
"I was running really late today so to get to school i had to shacockle out of my driveway."
"I had to get to bed early last night, so when me and my gilfriend were dry humping i had to hurry up and shacockle so i could get some sweet shut-eye."
