NAGMF Pronouced Nag-muff is an acronym which stands for Non-Ass Getting Mother Fucker. A NAGMF is a fella that lacks the ability to sexually attain members of the opposite sex. A NAGMF will usually spend his evenings drinking heavily and bullshitting with his fellow NAGMF's; which will usually lead to his eventual forgetting of why he went out in the first place-to find women.
