i used to do exactly this as an undergrad! i thought it made my writing sound whimsical or whatever, as if emulating the style of Lemony Snickett or _why the lucky stiff
i've since replaced this (bad imho) habit with other bad habits, fortunately
It goes without saying you shouldn't imitate the style of other people but have your own. Also, there's actually a feeling of joy in writing good prose and seeing the result, which is something I never mastered in English, as evidenced for example by my repeated use of "but", but (yeah..) kind of did in my native language.
