like it was going out of style

Describing something being done with extreme urgency, as though it was the last chance to do it. This ungrammatical expression and the synonymous like there’s no tomorrow date only from about 1970 but are well on their way to becoming clichés. They are used in such contexts as “He’s spending his trust fund like it was going out of style” or “They attacked the buffet table like there’s no tomorrow.” Purists frown on the conjunctive use of like (instead of as) but the clichés persist.
