When a younger guy gets 2 older girls back in his room, in walz or prosser (where upperclassman girls are always embarrassed to be). He then proceeds to hookup with both of them at the same time. Terms like "extra mayo" are thrown around towards the end of this "5 course meal." Then the guy wakes up in the morning sandwiched between these two chicks in his tiny twin sized bed.
"Hey man, thanks for not coming back to school until today, I muhlenbergered the hell out of these two upperclass chicks last night, there might be mayo on your bed."
"Oh, well at least you didn't starve last night."
