Erpewijk
Erpewijk is a last name strategy you could use if you and your partner wants to make up a new last name by combining the ones that you already have. The two persons who made this up's last names where Eriksson and Persson, so they took the two first letters of their last names and then they added Wijk.
"Are you and your husband doing a erpewijk when you get married?"
"Maybe, my last name is Lopez and my husband's is Anderson so our erpewijk would be Anlowijk."
"Love it!"
