what does mean "i will blast you" and "im gonna to rip you off"?
i am not sure "i will blast you " means "i will hit u or i will yell at u" and is that "rip u " means i will kill u or i will thwart or thrash u ?

Question

Answer

I will blast you...... in this context it could mean.... I will hurt you, kill you...

I will hit you... is to cause harm to someone, strike someone with your fists or a weapon...

I will yell at u.... where "u" is written slang for "you" and this phrase means to speak loudly at someone.

I will rip you off... this means you will steal from someone, take from someone

Answer

is it bad to follow that pattern?

Answer

By the way, never write 'u' or 'ur'. That's only done by small children and teenagers.
