Is what Ry Bleckel is when you date him and text him ily. He'll get pissed and say that you don't have a right to tell him you love him because you barely know him. Even though you've known eachother for about a year and are actually in a relationship. Then believe it or not, he'll break up with you right after and block you on all social media accounts. All because of a text message "ily."
Ex-girlfriend: "Did you hear about what Ry did last night?"
Friend: "Yes! He is such a jerk."

In medival Europe,masturbation was considered to be on the brink of insanity. So as an insult, people would call each other "jerk-offs", and soon, jerk was enough to get the point across.

A very powerful word to call someone... Unlike the f-word, "jerk" doesn't lose it's power the more you say it.
