one possiblity, there are probably others

(I assume you mean always selectin the same option (e.g. the first option) for each question with the objective of completing the survey as quickly as possible.

Incidentally, the broader name for this sort of behaviour (and other sorts of intentional and unintentional 'improper' patterns of responding to surveys is apparently 'satisficing' (a coined word if there ever was one) -- see:

We suspected a potentially high rate of satisficing due to the length and complexity of the survey. Mean completion times were suspiciously low, alerting us that there might be significant data quality issues. Looking for bimodal distributions of completion times to help identify speed-clickers.
Examination of verbatim and continuous variable responses showed that 5 identical response patterns were each repeated dozens of times in the dataset…accounting for more than 200 records. All cases were the result of a single gamer, using keystroke automation software to auto-fill the survey repeatedly.

Oops -- satisfice seems to be a legitimate word. The Oxford dico defines it as 'decide on and pursue a course of action that will satisfy the minimum requirements necessary to achieve a particular goal'.
