Perro de agua
Derived from the insult becerro de playa (beach calf), this refers to a dull, unimaginative person who is a constant killjoy or who always fucks with your life. It is used as a descriptor or combined with other insults for emphasis. (In Venezuela, calling someone a becerro, or calf, is a common way to label them a fool, a snitch, or an annoying loser).
a: Man, you are a total perro de agua. b: You calf-cum-guzzler-perro de agua. (spoken as one continuous insult).
