Phishing involves sending out emails or setting up fake websites in hopes that someone, somewhere, will give away personal information or unintentionally give you access to their computer. Spear phishing is exactly the same thing, but done to target a specific user. This usually means disguising the phishing attempts as being from a user or service already trusted by the target (i.e. spoofing), often using social engineering strategies to tailor content to the target.
