Refers to a person who is a prospective "wing-man" for more than one person in a single night. Typically this person is the non-single party in the group. However, if more than one non-single party exists, they are usually expected to aid the single persons by collaborating and creating a "wingfellowship".
Person A and Person B are both single. Person C is not. Person C will be the wingfellow for both Person A & B.
