Word Origin for lid
mid-13c., from Old English hlid "lid, cover, opening, gate," from Proto-Germanic *khlithan (cf. Old Norse hlið "gate, gap," Swedish lid "gate," Old French hlid, Middle Dutch lit, Dutch lid, Old High German hlit "lid, cover"), from PIE root *klei- "to lean" (see lean (v.)), with here perhaps the sense of "that which bends over." Meaning "eyelid" is from early 13c. Slang sense of "hat, cap" is attested from 1896. Slang phrase put a lid on "clamp down on, silence, end" is from 1906.
flip one's lid
Also, flip one's wig; flip out. React very strongly or wildly, as with anger, surprise, or excitement; also, go crazy. For example, I'm going to flip my lid if he doesn't show up, or She really flipped out when she realized that she had won first prize, or I think Rob has flipped his wig. These slangy expressions, with their allusion to losing the top of one's head, date from the 1930s and 1940s.
