Jimjar: the preferred word of jockstraps and other muchachos. It is a very powerful word and can only be used with permission from certain people (those chosen people know who they are and who they can grant access to the word to). There is a Jimjar alliance and if u ever say the word in distress, Mermaid Man and Barnacle Boy will come to your aid as long as you are underwater. Mermaid Man and Barnacle Boy will almost always come to your aid as long as Spongebob is not blowing the conch shell for their assistance.
Holy Jimjar! You need to grow a pair!
