我们滥情

Direct translation: 'We are sentimental.' Sentimentality may refer to excessive expression or feelings. For example, the owner of this username could be very expressive about feelings and loves towards other people; on the other hand, it may be a humorous way to say that oneself falls in love easily. But note that '滥' generally has a pejorative connotation which implies improper use or excessive quantity, so this username could be taken negatively or sarcastically.
