Since they 'woke' to 'Lady' being a four letter word, UL is handcuffed in using 'Women' as a descriptive, which in turn forces a 'Men' descriptive simply because there are 'two' versions of "basketball at UL."
To save typing WBB and MBB are often used to differentiate between the two basketballs at UL.
If there were a men's softball at UL the same would be needed for WSB but since Women's softball rules the roost SB is sufficient.
Same for baseball. there is only one baseball so BB is sufficient.
MBB and WBB differentiate the two basketballs at Louisiana. Men and Women's.
Everthing is in context.
