sklonklish means: It’s a crummy, cruddy and crappy product that is otherwise very poor. The term was invented to mock teenage slang and first appeared in 1947 RKO movie “The Bachelor and the Bobby-Soxer”, starring Shirley Temple, Myrna Love, and Cary Grant. The opening scene features Temple as Susan Turner. She protests her maid being awakened by Temple and says, “But Bessie! I am absolutely sklonklish.” Moments later when Bessie, playing Temple, wakes Susan Turner’s younger sister Judge Margaret Turner (played by Loy), she says to her, “Next time she claims she feels sklonklish. You tell her to not be a clunk.” “. (in Community Dictionary, added by Gema Soto)
