In the Western world, it's almost customary to use the term 'Bro' as a way to greet, express gratitude, or show agreement with someone.
Is 'Bro' different from 'Pro'?
'Pro' is the abbreviation of 'Professional' in English. When translated into Vietnamese, it means professional or highly skilled. Vietnamese youth often use this term to refer to or praise individuals with high expertise, and in the gaming community, 'Pro' is used to commend outstanding gamers.
- Reference: What is Pro?
Fundamentally, Bro stands for Brother, translating to elder brother, sibling, while Pro is an abbreviation for Professional, referring to someone with high expertise. However, when these terms are introduced to Vietnam, a portion of Vietnamese youth, not proficient in English, may easily confuse and misuse Bro and Pro in various contexts.
Typically, you might notice some using Bro instead of Pro to praise those who excel in their expertise. Yet, using Bro is incorrect. To commend those who are outstanding, we should use Pro instead of Bro. Moreover, if the intention is to express intimacy, closeness, and respect, then using Bro is appropriate.
