What exactly means to describe someone saying "圧が強い" (atsu ga tsuyoi) . I know that's something related with "the person has a strong pressure" or "the pressure in that person is strong" but I was wondering about what is the real connotation for this expression.
Basically this 圧 is a figurative and humorous expression that refers to one's "energy" or "aura". The implication of 圧が強い depends on the context. If it's negative, it implies "oppressing", "noisy and annoying", "scary", "over-confident and rude", etc. If it's neutral or positive, it implies "eager", "looks full of confidence", "has strong presence", etc. This is a rather recent slangy expression, and it's probably not included in a serious dictionary.
