ёбнуть

To whack, to hit, to smack; to down/chug (a drink), to drop/slam down; to explode/blast; to do something suddenly. Derived directly from the core, highly productive mat root еб- / ёб- (to fuck), combined with the single-action perfective suffix -нуть. It is one of the most frequently used, high-energy perfective verbs in the entire Russian lexicon of profanity, possessing an incredibly wide array of contextual meanings: first, to physically strike, punch, or hit someone or something hard (он его ёбнул по голове — “he whacked him over the head”); second, to down an alcoholic beverage quickly (давай ёбнем по рюмке — “let’s down a shot”); third, to accidentally drop, slam, or break an object (я ёбнул телефон на асфальт — “I slammed my phone onto the asphalt”); fourth, to detonate, explode, or make a loud, sudden crash (e.g., lightning, bombs, or fireworks).

Если не работает бензонасос… надо выйти и ебнуть по нему молотком… тогда включается…

If the fuel pump does not work… you have to get out and bash it with a hammer… then it will turn up…

To go crazy, to lose one’s mind, to freak out; to fall hard, to wipe out; to be dumbfounded, to be shell-shocked. Derived from the primary mat root ёб- (associated with the sex act), combined with the reflexive suffix -ся to form a highly versatile and expressive verb. In everyday slang, it carries three main meanings: first, it means to lose one’s sanity, act irrationally, or fly off the handle (ты что, ёбнулся? — “have you completely lost your mind?”); second, it denotes a violent physical fall or crash (он поскользнулся и ёбнулся со лестницы — “he slipped and wiped out down the stairs”); third, it expresses extreme shock or disbelief at sudden news (я просто ёбнулся, когда узнал цену — “I was absolutely shell-shocked when I found out the price”).

Чтобы я не ебнулся в открытый колодец. Я молился, чтобы просто дойти до ближайшего освещенного тротуара.

So I wouldn’t fall into an open well. I prayed just to reach the nearest lit pavement.

Шейх ёбнулся совсем! Арабский шейх написал свое имя на песке буквами километровой высоты.

The sheikh is totally bonkers! An Arab sheikh wrote his name in the sand in letters a kilometre high.
