recessive defect meaning that both copies of the chromosome must have the defect before it can be expressed. Females who have one X chromosome without the defect do not get this disease. Males, since they only have one X chromosome, get the disease
Normally sex-linked traits are carried only on the X chromosome, meaning a sex-linked gene can only be inherited from the father's X or the two mother's X's. However, there are occasions where the trait is carried down by the Y chromosome, meaning only the males would inherit it, and it would be expressed. This is very uncommon because the Y chromosome carries very little genetic material/information in comparison to the Y chromosome.
You can't catch it, it's a chromosomal disorder meaning you only have 1 X chromosome.
