Kissing, touching, rubbing, licking, massaging...just to name a few.

Cute clothes and spontaniously kissing and groping your partner while hiding behind clothing racks in a store, then following through later at home!

Wow so many...it can be physical (kissing, rubbing/fondling/massaging, stripping, dirty dancing, spanking, tying up, dressing up, etc etc) mental/verbal with dirty talk or letters or emails or sending hot pics of yourself to him/her.

Whether an act constitutes foreplay depends on the intent. If no intimate sexual acts are intended, foreplay-type actions are often classified as flirting or, in colloquial terms, being "touchy-feely". Foreplay is often subtle in its initial stages. Even before the partners are together, foreplay can be introduced by the selection and creation of a particular environment. A romantic, intimate, or overtly sexual atmosphere can be considered a gesture of foreplay. Foreplay can begin with non-physical behavior that signals sexual availability. Verbally, foreplay may include sexual compliments, subtle comments with double entendre, and intimate conversations. Non-verbally, foreplay can include provocative clothing, preening gestures, licking or biting one's lips, standing inside a partner's personal space, and holding a gaze longer than is acceptable for casual acquaintances. If the potential partner accepts the sexual invitation, foreplay has begun. Acceptance is often indicated by reciprocating with similar behavior. Since these interactions are non-explicit, there can be misunderstandings about whether an invitation has been extended or accepted. Inadvertent or not, this kind of miscommunication is often termed "leading someone on". Foreplay eventually turns physical. Simple and seemingly innocuous acts, such as straightening someone's clothing or hair, bumping into someone while walking, stroking someone's arm, or whispering in someone's ear can constitute foreplay. One may also hold hands, touch the face, kiss, "bite", or massage. As comfort increases, the level of intimacy usually increases. More intimate examples include: Deep tongue kissing, also known as French kissing; Touching and massaging erogenous zones over clothing, also known colloquially as groping or petting; Touching and massaging erogenous zones under clothing, or heavy-petting; Rubbing together erogenous zones over clothing, also known as dry humping or grinding; Undressing oneself or partner, also known as stripping; Oral sex. Direct manipulation of naked erogenous zones is almost always considered foreplay. In women, this includes stimulation of the clitoris and vulva. In men, it includes stimulation of the penis and scrotum. For both sexes, it includes stimulation of nipples and anus. Stimulation can be achieved by mouth, hands, sex toys like dildos or vibrators, or common household objects like feathers or ice cubes.
