A bachelor pad is a home (pad) in which a bachelor or bachelors (single men) live. The exact standards on what constitutes a bachelor pad are often ambiguous and debated but one definition describes it as:
A "bachelor pad" is a slang term for a living space owned by a bachelor (single man) that is designed as a collective space (as opposed to individual items) with the purpose of facilitating a bachelor in his daily activities to include but not limited to daily functionality, use of free time, hobbies and interests, entertaining friends, and seducing women. A bachelor pad can be done on a very limited budget as is the case with many young adults and college students, or to an extravagant level as seen amongst some celebrities.[1]
It should not be confused as such with "bachelor apartment", a real estate term which refers an apartment with no bedroom –the main room serves as a bedroom, living room, and dining room (and sometimes kitchen as well).
