Taking into account that shortly before this consultation another one appeared for "matron", it is possible that it is a trolling imitating some diminutive also from mother (for the Latin mater), which also suggests that it may be a vulgar variant of license plate that is used in . . . somewhere. Apart from the rambling, it can be an error by metric, marica, rattle. . .
