The tactics used by Kennard included a request for full reading of a bill on re-inspection of motor vehicles following collisions. Kennard also proposed an amendment, with long explanations, to that measure.

The Art and Etymology of Chubbing
The capitol’s gone chubbing. Depending on your understanding of the term “chubbing” that could mean anything from fishing, engaging in a variety of legislative delays or sexual activities.
 
The best I can tell the word “chubbing” has it’s origins in the Scandinavian word for the chub fish. A chub is a small but fat fish that is said to be named from its large head, but it is rather its body which is thick and fat. This should not be separated from the adjective chubby (i. e. fat or fleshy).
 
In fishing nomenclature “going chubbing” means going fishing for the chub fish. The chub is primarily a river fish.
 
It is curious indeed that we have gone for a term for fishing for a particular kind of fish to the present describing a form of legislative filibustering - a delay tactic by excessive talking, questioning or filing unnecessary amendments.
