harry probably found out about the name fleamont just before albus severus was born and ginny, who has a penchant for weird names (hello pigwidgeon) probably pounced on it and was like YES LETS CALL OUR SON THIS, THIS IS A V GOOD NAME
and harry was like 'no ginny i'd rather name him after snape'
and ginny got an evil glint in her eye and was just like 'okay have it your way then, we shall call him albus severus'
and then harry spent the rest of his life trying to decide which one was worse: albus severus or albus fleamont
(albus prefers fleamont)
