Caulk

Caulk; A funny word that has the same pronunciation as the male genitalia, however instead of the off-putting, expected meaning, it is merely a form of plaster used for house and bathroom repair.

(note: Amazing for joking with friends! Example as follows;)

*Man one*: "Hey Non-disclosed friend, wanna see a picture of my caulk?"
*Man two*: "Hell no Equally non-disclosed friend! That is very disgusting and inappropriate!"
*Man one*: *shows picture of completely innocent repair tool known as "Caulk"*
*also Man one*: "See? This is my completely innocent repair tool known as 'Caulk'"
*Man two*: "Ha Ha Ha, This is very humorous. Thank you for showing me this example of great humor my good Non-disclosed friend"
