This is a term coined to identify things like jiggling breasts, cleavage shots, panty shots, bra shots, closeup shots of women's breast, legs, butt, etc., and mild nudity all for the purposes of "servicing" the audience and having no relevance to the plot or characters of a series. The term has a second meaning covering things like massive action sequences, explosions, fights, etc., but it mostly refers to the first meaning.
This is a genre of anime which features mechanical fighting machines. Often these take the form of giant robots but this isn't the only form mecha can take. There are tons of examples of mecha titles considering the popularity of the series. Blue Gender, Shin Seiki Evangelion, Tenkuu no Escaflowne, and Bubblegum Crisis Tokyo 2040 are all classic mecha titles.
