jodidamente
/xoˌdidaˈmente/ · B1 · adv
fucking
jodida (fucked, from joder) + -mente (-ly) = fuckingly
Spanish makes adverbs by adding -mente to the feminine adjective, as in rápida → rápidamente. Joder comes from Latin futuere, 'to have sex'. So jodidamente works like 'fucking' as an intensifier: es jodidamente difícil = it's fucking hard.
