Somebody who is not obese but has a gut. The majority of their fat is held in their belly area including the back love handles. They do not have overwhelming tit size however their gut is prominent. A blubgut will also like to indulge in many types of treats like hotdogs, beer, brownies, sandwiches, pizza, french fries, and fast food. They will also enjoy a goodlaugh and have an overall cheery disposition. A blubgut also attempts to make his treats seem healthy, but they are not. Blubguts are also easily flustered by touching their fat regions.
The worthless fat above a womans pelvic area. It is the rather large size roll below her tummy, and while running your hand downward it makes the sound of BLUBUMP!! In order to have sex with a woman wearing a blubump you must first lift it out of the way in order to gain access to the vagina.The un-official name for it is a front-butt.
Bulublu is used when someone is so sad that the word "sad" is too much of an understatement.
Can aleso be used instead of words like weird, bad, horrible or annoying.
If two people are really close it can be used as a nickname.
OMG he cat died that is so blublu.
Awe you're so sweet you little blublu.
