“Squirt” is often used as a term of endearment for little kids or babies. It’s also defined as a “gushing of liquid”. It also has sexual connotations, as evidenced by the internet. Whatever you do, don’t do a Google search unless you want to get some results that are less than work safe. Technically speaking, we all are Daddy’s “squirts”. That’s disgusting to think of from both a child and a father standpoint. It’s a little distasteful, but we’ve included an anthropomorphic sperm on this Daddy's Little Squirt Romper to make things less gross.
Squirt is just one of those words that sounds kind of perverted when you use it. You have to use it in the right context or else it sounds weird. How about this: “We squirted out this daddy baby bodysuit”. Nope, that doesn’t sound right at all. Now that we think about it, you should only use the word “squirt” when talking about water.
