Use of catchphrase or takiya kalam
You might have noticed that some people use some specific words or phrases while talking to you or anybody else. Are you also accustomed to using any specific word in normal conversation with other people?"Takiya Kalaam" or catchphrase is a word or a set of words used by people while speaking. These words are used so many times that they become a signature of that person. The word Takiyaa is an Urdu word. It means a pillow. It is used for relaxing. I am not 100% sure but I believe that catchphrase is a kind of resting space for speakers while speaking. It helps to fill the gap between words while the speaker is thinking something.
They are so habituated that they don't even realise that they use it so often. For example, some people say, "You See…" very often… almost in every sentence. My friend says, "You see…" so often that he is nicknamed "You See". Azharuddin, former Indian cricket captain used to speak " But" almost in every sentence.
Other common Takiyaa Kalaams are, "for example", "generally", "usually" "most probably", "understand", " by God", " for God sake", "got it"," catch", "I think"," Do not mind", "Oh I see", Can't say" and so on.
Some common Hindi Takiyaa Kalaams are, "Main keh rahaa hoon", "suno naa", "achchhaa", "Kasam se", "Bhagwaan Kasam"," samjhe", "therek he na", " hanji" "samjhe ke na", " ennnn", "na na an".
