ligvi.

liglig: [20] The verb lig, meaning ‘freeload, sponge’, and its derivative ligger, achieved a particular prominence in late 20th-century British English. But in fact its roots go back far into the past. In origin it is simply a variant version of the verb lie ‘recline’. In Old English times this was licgan, and although in the mainstream language licgan became lie, liggen survived dialectally. The sense ‘lie about’ passed naturally into ‘lounge about lazily’, and apparently merged with another dialectal sense ‘steal’ to produce the word’s current meaning.=> lie
