A Berwald is an extremely tall guy, usually with blond hair and glasses, who keeps a scary expression most of the time. Underneath his scariness, he is a real sweetheart and is very reliable. Berwalds have a tendency to claim people as their "wife" and will most likely stay with and protect that person with their lives.
The Bertle is a rotund, pear like torso. It's not until you see the Bertle 'front on' does one understands the extent of 'over weight' which stretches out from the stomach to the love handles (or belly ears).
The bertle is a more solid and structured belly fat.
This is why, against the laws of gravity, the belly weight does not 'overhang' the waist line, instead it curves upward, like the base of a wine glass.
Example 1:
