When a man believes he is running a tight ship but in reality his girlfriend is the one who calls the shots in the relationship.
Depending on the level of control the girlfriend exerts, the man maybe designated as one of the following;
1. Sailor Pants
2. Captain Pants
3. Admiral Pants
And the ultimate....
4. Lord Nelson Pants
'Hey Captain Pants, would you like a Baby Sham?'
Alternatively when referring to the individual, his 'Pants Rank' is sufficient;
'Sailor, what time is your Mrs arriving?'
'I hear Alicia moved in and promoted Matt to Admiral... suppose that's the last we will see of him'
