It's a classic case of glomming: Americans seized on glaum (a term from Scots dialect that basically means “to grab”) and appropriated it as their own, changing it to glom in the process. Glom first meant “to steal” (as in the purse-snatching, robber kind of stealing), but over time that meaning got stretched to include figurative uses. Today the term is most familiar in the phrase “glom on to,” or “glom onto,” which can mean “to appropriate for one's own use,” as in “glomming on to another's idea”; “to grab hold of,” as in “glommed onto the last cookie”; “to latch on to,” as in “glom on to an opinion” or “glom onto an influential friend”; or “to become aware of,” as in “glomming onto the potential of this new technology.”
