When a girlfriend makes nachos for a party or group of other people instead of making them for her boyfriend. An extreme slight, especially when said boyfriend has been asking for them for ages.
Boy: Hey do you think I could have nachos later?
Girl: Sure, i'll make them for the party on Saturday.
Boy:...Nacho Cheating
Girl: Sure, i'll make them for the party on Saturday.
Boy:...Nacho Cheating
