A shamewank can be defined by the distraught feeling you get after masturbation, knowing that your belly is covered in cum having thought about the most disgustings thing ever.
Examples of these are:
Your dog
Your cat
Your best friends girlfriend
Your best friend (Same sex)
Your mum
Your sister
The 80 year old woman down the road
Dead people
