Crawling

Crawling is a form of moving around by some animals and in some cases by humans.

For humans it usually means moving on knees and hands, with support from the toes. Without vehicle and without being carried by an animal it is the main alternative for walking and running, mainly when the person is not capable of walking because of being an infant or due to a disability or being wounded or sick. It is also applied in very low places (a cave, under a table, etc.), when searching for something on the ground, and for fun, including playing a submissive role in BDSM.

Figuratively, crawling means moving slowly.

Crawling is also a song by the nu-metal/rap metal band Linkin Park.
