My Russian friend told me "я ухажеру бороду отбила". What did she mean? She told me this after I told her I got in a fight.
Your example can literally be translated as "I've hit my admirer in the chin real hard".
"Ухажер" is a colloquial for "admirer".
"Борода" is used as a synonym of the word "подбородок", which means "chin".
The trickiest word to translate is "отбить". Here is used in the meaning "hit smth so hard that it hurts very much". Usually, the word "отбить" is used not when you hit someone, but when you hurt yourself, e.g.
Он неудачно прыгнул и отбил пятки.
He jumped unfortunately and hurt his heels.
But, as in your example, it can also be used to refer to the actions directed at other people.
